N* physics and nonperturbative quantum chromodynamics : proceedings of the joint ECT*/JLAB workshop, Trento, Italy, May 18-29, 1998 by S Simula( Book )

1 edition published in 1999 in English and held by 87 WorldCat member libraries worldwide

The workshop was devoted to a summary of recent experimental and theoretical research on N* physics. Special emphasis was given to the information that photo- and electro-production of nucleon resonances can provide on the non-perturbative regime of quantum chromodynamics. Discussions among experimentalists and theoreticians were stimulated in order to pursue the interpretation of the huge amount of forthcoming data from several laboratories in the world. This volume contains both the invited lectures and the contributions. On the main topics, like single and double pion production, pi- and K-meson production, the GDH sum rule, and the spin of the proton

Hadron structure with light dynamical quarks( )

3 editions published in 2005 in English and held by 6 WorldCat member libraries worldwide

Generalized parton distributions encompass a wealth of information concerning the three dimensional quark and gluon structure of the nucleon, and thus provide an ideal focus for the study of hadron structure using lattice QCD. The special limits corresponding to form factors and parton distributions are well explored experimentally, providing clear tests of lattice calculations, and the lack of experimental data for more general cases provides opportunities for genuine predictions and for guiding experiment. We present results from hybrid calculations with improved staggered (Asqtad) sea quarks and domain wall valence quarks at pion masses down to 350 MeV

Effect of Atomic Hydrogen Exposure on Electron Beam Polarization from Strained GaAs photocathodes( )

3 editions published in 2003 in English and held by 0 WorldCat member libraries worldwide

Strained-layer GaAs photocathodes are used at Jefferson Lab to obtain highly polarized electrons. Exposure to atomic hydrogen (or deuterium) is used to clean the wafer surface before the activation with cesium and nitrogen trifluoride to consistently produce high quantum yield photocathodes. The hydrogen-cleaning method is easy, reliable and inexpensive. However, recent tests indicate that exposure to atomic hydrogen may affect the polarization of the electron beam. This paper presents preliminary results of a series of tests conducted to study the effect of atomic H exposure on the polarized electron beam from a strained-layer GaAs sample. The experimental setup is described and the first measurements of the beam polarization as a function of exposure dose to atomic hydrogen are presented
Effective Field Theory and Isospin Violation in Few-Nucleon Systems( )

2 editions published in 2004 in English and held by 0 WorldCat member libraries worldwide

I discuss the leading and subleading isospin--breaking three--nucleon forces in the chiral effective field theory framework. I have discussed the leading and subleading isospin-violating 3NFs. The leading contributions are generated by one- and two-pion exchange diagrams with their strength given by the strong neutron-proton mass difference. The subleading corrections are again given by one- and two-pion exchange diagrams, driven largely by the charged-to-neutral pion mass difference and also by the electromagnetic neutron-proton mass difference and the dimension two electromagnetic LEC f₁. In the future, these isospin-breaking forces should be used to analyze few-nucleon systems based on chiral EFT
Recent Results from JLab on Nucleon Responses( )

2 editions published between 2003 and 2004 in English and held by 0 WorldCat member libraries worldwide

Highlights of recent data from Jefferson Lab on the nucleon response to an electro-magnetic probe are presented. Recent technological advances in polarized beams and either polarized targets or nucleon recoil polarimeters have yielded a significant improvement on the precision of the data. An outlook is presented of planned experiments
3He(e, e'p)d and 3He(e, e'p)pn at High Momentum Transfer( )

4 editions published between 2003 and 2004 in English and held by 0 WorldCat member libraries worldwide

The (e, e'p) reaction has proven to be a useful tool for studying specific aspects of the nucleus. The Jefferson Lab continuous electron beam accelerator facility (CEBAF) along with the high resolution spectrometers in the Hall A end station allow this reaction to be studied in kinematics heretofore unaccessible. In this paper the results of the Jefferson Lab Hall (almost equal to) A ³He(e, e'p)d and ³He(e, e'p)pn measurements, performed at a fixed q=1.5GeV/c and omega=840MeV, will be presented along with theoretical calculations by G. Salme, J.-M. Laget, and J. Udias
Fabrication and Testing of the SRF cavities for the CEBAF 12 GeV Upgrade Prototype Cryomodule Renascence( )

2 editions published in 2005 in English and held by 0 WorldCat member libraries worldwide

Twelve seven-cell niobium cavities for the CEBAF 12 GeV upgrade prototype cryomodule Renascence have been fabricated at JLab and tested individually. This set includes four of the ''Low Loss'' (LL) design and eight of the ''High Gradient'' (HG) design. The fabrication strategy was an efficient mix of batch job-shop component machining and in-house EBW, chemistry, and final-step machining to meet mechanical tolerances. Process highlights will be presented. The cavities have been tested at 2.07 K, the intended CEBAF operating temperature. Performance exceeded the tentative design requirement of 19.2 MV/m CW with less than 29 W dynamic heat dissipation. These results, as well as the HOM damping performance are presented
Polarisation Transfer in Proton Compton Scattering at High Momentum Transfer( )

3 editions published in 2004 in English and held by 0 WorldCat member libraries worldwide

The Jefferson Lab Hall A experiment E99-114 comprised a series of measurements to explore proton Compton scattering at high momentum transfer. For the first time, the polarisation transfer observables in the p (~ 0 ~ p) reaction were measured in the GeV energy range, where it is believed that quark-gluon degrees of freedom begin to dominate. The experiment utilised a circularly polarised photon beam incident on a liquid hydrogen target, with the scattered photon and recoil proton detected in a lead-glass calorimeter and a magnetic spectrometer, respectively
Physical Nucleon Form Factors from Lattice QCD( )

3 editions published in 2005 in English and held by 0 WorldCat member libraries worldwide

We explore the possibility of extrapolating state of the art lattice QCD calculations of nucleon form factors to the physical regime. We find that the lattice results can be reproduced using the Light Front Cloudy Bag Model and the Extended Gari-Krmpelmann Model by letting their parameters be analytic functions of the quark mass. We then use the models to extend the lattice calculations to large values of Q{sup 2} of interest to current and planned experiments. These functions for the first model are also used to define extrapolations to the physical value of the pion mass, thereby allowing us to study how the predicted zero in G{sub E}(Q{sup 2})/G{sub M}(Q{sup 2}) varies as a function of quark mass
Excited Baryons and Chiral Symmetry Breaking of QCD( )

3 editions published between 2002 and 2003 in English and held by 0 WorldCat member libraries worldwide

N* masses in the spin-1/2 and spin-3/2 sectors are computed using two non-perturbative methods: lattice QCD and QCD sum rules. States with both positive and negative parity are isolated via parity projection methods. The basic pattern of the mass splittings is consistent with experiments. The mass splitting within the same parity pair is directly linked to the chiral symmetry breaking QCD
