Particle fever by Mark A Levinson( Visual )

3 editions published between 2013 and 2014 in English and held by 109 WorldCat member libraries worldwide

"PARTICLE FEVER gives audiences a front row seat to our generation's most significant and inspiring scientific breakthrough as it happens. The film follows six brilliant scientists during the launch of the Large Hadron Collider, marking the start-up of the biggest and most expensive experiment in the history of the planet. 10,000 scientists from over 100 countries join forces in pursuit of a single goal: to recreate conditions that existed just moments after the Big Bang and find the Higgs boson, potentially explaining the origin of all matter. But our heroes confront an even bigger challenge: have we reached our limit in understanding why we exist? PARTICLE FEVER is a celebration of discovery, revealing the very human stories behind the tale of this epic experiment."--Container

The presence of many axion fields in four-dimensional string vacua can lead to a simple, radiatively stable realization of chaotic inflation
Stopping Gluinos( )

1 edition published in 2005 in English and held by 5 WorldCat member libraries worldwide

Long lived gluinos are the trademark of split susy. They form R-hadrons that, when charged, efficiently lose energy in matter via ionization. Independent of R-spectroscopy and initial hadronization, a fraction of R-hadrons become charged while traversing a detector. This results in a large number of stopped gluinos at present and future detectors. For a 300 GeV gluino, 10{sup 6} will stop each year in LHC detectors, while several hundred stop in detectors during Run II at the Tevatron. The subsequent decays of stopped gluinos produce distinctive depositions of energy in calorimeters with no activity in either the tracker or the muon chamber

Particle physics in the 21st century by Savas Dimopoulos( Visual )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

Professor Savas Dimopoulos of Stanford University discusses that elementary particle physics is entering a spectacular new era in which experiments at the Large Hadron Collider (LHC) at CERN and at astrophysical observatories will soon start probing some of the most profound questions in physics, such as: Why is gravity so weak? What is the origin of mass? What is the Dark Matter of the Universe? Are there new dimensions of space? Can we produce black holes and strings in the lab? Are there other parallel universes, each with different laws of Nature? LHC is expected to shed light on such questions and lead to a new deeper theory of particle physics. Surprisingly, recent developments suggest that the principle of minimalism which has been driving scientific thinking for centuries, is losing ground to the old principle of plenitude, as the complexity of the extra dimensions in string theory suggests the existence of a plethora of ultra-light particles with exciting observational signatures in Cosmology, Astrophysics and at the LHC
Towards precision tests of general relativity using an atom interferometer by Jason Michael Hogan( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

A 10-meter tall, dual-species atomic fountain gravimeter was designed and built for the purpose of testing the Equivalence Principle with freely-falling atoms. Once completed, the apparatus promises to be the most sensitive atom interferometer ever built, with a projected differential acceleration sensitivity of 10^-15 g. This phenomenal force sensitivity opens the door to exciting science applications which are reviewed, including setting new limits on the Equivalence Principle, measuring effects of General Relativity in a laboratory setting, and detecting gravitational waves
A sensitivity study of the LIdar-Radiometer Inversion Code (LIRIC) using selected cases from Thessaloniki, Greece database( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

ABSTRACT: We investigate the uncertainty introduced to the optical and microphysical properties estimated with the lidar radiometer inversion code (LIRIC) by user-defined input parameters based on measurements carried out with a multi-wavelength Raman lidar and a sun photometer located at Thessaloniki, Greece (40.6° N, 22.9° E, 60 m above sea level). The sensitivity study involves three tests. We first evaluate the selection of the regularization parameters needed for the algorithm to initialize the iteration process. The latter two tests consider the impact of the boundary limits at the top/bottom (upper/lower limit) of the signal to the derived concentration profiles. The aforementioned tests were applied to two different cases, a Saharan dust event and a continental pollution case. We concluded that the largest uncertainties are introduced when varying the lower limit (more than 35%) regardless of the aerosol type or mode (fine/coarse). Varying the regularization parameters resulted in an uncertainty of 20%, and the selection of upper limit led to discrepancies of less than 3%. In conclusion, this sensitivity study indicates that future LIRIC users should apply an overlap function to the lidar signals before applying the methodology for minimizing the uncertainties in the near range
Extending the supersymmetric little hierarchy by Kiel Howe( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Particle physics describes particles and their interactions at many energy scales, and different models can be characterized by the relationships between these scales. In a natural model, particle properties are insensitive to perturbations at higher energy scales, while in a tuned model particle properties are determined by delicate cancellations between processes even at energy scales separated by large hierarchies. Is our universe natural or tuned? The answer to this question can have dramatic consequences for the interpretation of fundamental theories and for our understanding of the inflationary birth of our universe. The discovery of a Standard Model-like Higgs Boson at the CERN Large Hadron Collider (LHC) has made concrete the possibility that our universe may be tuned. However, the observed particles of the Standard Model may still form part of a natural model if new particles and symmetries are present at energies observable at the LHC and future colliders. Supersymmetry is one possible extension of the Standard Model motivated by the idea of naturalness, but its minimal version is highly constrained by searches from the first run of the LHC. We describe extensions of the minimal supersymmetric model in which a little hierarchy between the masses of the new supersymmetric particles and the Standard Model particles is consistent with naturalness and current LHC searches. We also discuss the potential for discovering these models in the upcoming collisions at the upgraded LHC and future colliders
Towards a precise theory of cosmology by Daniel Lord Harlow( )

1 edition published in 2012 in English and held by 1 WorldCat member library worldwide

In this thesis I discuss progress towards a precise mathematical description of cosmology and in particular of eternal inflation. I present a conjecture for a necessary condition for a spacetime to have a precise dual description, discuss how the dictionary of dS/CFT is more sophisticated than that of AdS/CFT, present a soluble model of eternal inflation that has a conformal boundary theory at future infinity, and discuss the implications of this model for a conjectured precise dual theory based on observers in bubbles with zero cosmological constant. The work described was done in collaboration with Leonard Susskind, Douglas Stanford, and Stephen Shenker

Searches for light scalar dark matter by Ken Van Tilburg( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

If the dark matter is made up of a bosonic particle, it can be ultralight, with a mass potentially much below 1 eV. Moduli fields, whose values could set couplings and masses of known particles, are good candidates for such light dark matter. Their abundance in our Universe would manifest itself as tiny fractional oscillations of Standard Model parameters, such as the electron mass or the fine-structure constant, in turn modulating length and time scales of atoms. Rods and clocks, used for gedanken experiments in the development of relativity theory, have since transformed into actual precision instruments. The size of acoustic resonators and the frequency of atomic transitions can now be measured to 1 part in 10^24 and 10^18, respectively, and thus constitute sensitive probes of moduli. Atomic gravitational wave detectors can have a time-domain response to modulus dark matter, and sense temporal oscillations of atomic frequencies down to 1 part in 10^25. This thesis gives an overview of the parameter space of modulus dark matter, and compares the sensitivity of various experimental proposals relative to existing constraints from searches for new forces. I will focus on two classes of experimental strategies in particular: resonant-mass detectors (rods), and atomic spectroscopy and interferometry (clocks)
The search for dark matter : from colliders to direct detection experiments by Mariangela Lisanti( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

This thesis is devoted to searches for dark matter at colliders and direct detection experiments. The first half of the work focuses on the Tevatron and LHC. Jets and missing energy searches at these colliders are sensitive to a broad class of models and dark matter candidates. I show that current jets plus missing energy analyses can miss signals for new physics, and suggest an alternative model-independent search strategy that broadens the reach of these experiments I also discuss searches for Higgs bosons that decay to light pseudoscalars. Information about the Higgs sector obtained through such searches may hint at the nature of the dark matter. The second half of the thesis turns to direct detection experiments, with a focus on inelastic dark matter. I discuss the prospects for discovering inelastic dark matter at upcoming experiments, and present two models with inelastically scattering dark matter. One of these models posits composite dark matter and has unique phenomenology that can be studied with directional detection experiments

Searching for the QCD axion with black holes and gravitational waves by Maria Baryakhtar( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Advanced LIGO may be the first experiment to detect gravitational waves. Through superradiance of stellar black holes, it may also be the first experiment to discover the QCD axion with decay constant above the grand unification scale. When an axion's Compton wavelength is comparable to the size of a black hole, the axion binds to the black hole, forming a ``gravitational atom.'' Through the superradiance process, the number of axions occupying the bound levels grows exponentially, extracting energy and angular momentum from the black hole. Axions transitioning between levels of the gravitational atom and axions annihilating to gravitons can produce observable gravitational wave signals. The signals are long-lasting, monochromatic, and can be distinguished from ordinary astrophysical sources. We estimate up to order one transition events at aLIGO and up to ten thousand annihilation events. In the event of a null search, aLIGO can constrain the axion mass for a range of rapidly spinning black hole formation rates. Axion annihilations are also promising for much lighter masses at future lower-frequency gravitational wave observatories; the rates have large uncertainties, dominated by supermassive black hole spin distributions. Our projections for aLIGO are robust against perturbations from the black hole environment and account for our updated exclusion on the QCD axion suggested by stellar black hole spin measurements
