And they discuss the enormous, high-precision experiments that particle physicists are undertaking to test the laws of physics at their most fundamental levels - and how their results reveal tantalizing new possibilities for solving this puzzle at the heart of the cosmos." "The Mystery of the Missing Antimatter is at once a history of ideas and an exploration of modern science and the frontiers of human knowledge. This book reveals how the interplay of theory and experimentation advances our understanding and redefines the questions we ask about our universe."--BOOK JACKET+-+84588664155719ocn041606304book20000.53Barnett, R. MichaelThe charm of strange quarks : mysteries and revolutions of particle physics"This is the story of how twentieth century physicists revealed layer upon layer of structure within the atom to reach the basic particles of matter. Both particle physics and cosmology are made accessible to a reader familiar with some basic principles of physics. The Charm of Strange Quarks relates the drama of the discovery of the charm quark, describes the ephemeral neutrino that can traverse the diameter of Earth, explores indications of dark matter and an accelerating universe, and then culminates with the discovery of the top quark and speculations about the existence of extra space dimensions."--BOOK JACKET+-+62433423853157ocn568512736com20080.76National Research Council (U.S.)NASA's elementary and secondary education program review and critique"This report focuses on NASA's K-12 education activities, as mandated by congressional language in the 2005 reauthorizing legislation for the agency"--from Introduction (p. 11)+-+060066458531ocn815563954com2007National Academies' Guidelines for Human Embryonic Stem Cell Research, The, 2007 Amendments, 2nd Edition to Guidelines for Human Embryonic Stem Cell Research, 030909653732ocn676324539book20050.47Kuōku no fushigi : Soryūshi butsurigaku no shinpi to kakumei11ocn751223103book20080.47Quinn, Helen RThe mystery of thw missing animatter+-+845886641511ocn841164690com20130.47Miyashita, Tomonari ScottMeasurement of CP-violating asymmetries in B^0 --> (rho pi)^0 using a time-dependent Dalitz plot analysisWe present results for a time-dependent Dalitz plot measurement of CP-violating asymmetries in the mode B^0 --> pi^+ pi^- pi^0, dominated by B^0 --> rho^\pm pi^\mp (rho^\pm --> pi^\pm pi^0) decays. Our dataset is derived from the complete sample of 471 x 10^6 B-Bbar meson pairs collected by the BABAR detector at the PEP-II asymmetric-energy e^+e^- collider at the SLAC National Accelerator Laboratory, operating on the Upsilon(4S) resonance. We extract parameters describing the time-dependent B^0 --> rho pi decay probabilities and CP asymmetries, including C, DeltaC, S, and DeltaS, finding these measurements to be consistent with the results of previous analyses. Additionally, we present a two-dimensional likelihood scan of the direct CP-violation asymmetry parameters for B^0 --> rho^\pm pi^\mp decays, finding the results to be consistent with direct CP violation at ~ 2 sigma significance. Finally, we present information on the CP-violating parameter alpha, corresponding to an angle in the unitarity triangle associated with the CKM quark-mixing matrix. We perform a likelihood scan of alpha that incorporates constraints from B^\pm --> rho pi measurements by means of isospin relationships. A robustness study assessing the reliability with which alpha is extracted provides important insights into the interpretation of this result11ocn862317993book20060.47Barnett, R.

We observe 1034 ± 131 signal decays, corresponding to a branching fraction of B(B^+ \to \omega\ell\nu) = (1.17 ± 0.15 ± 0.11) x 10^-4, where the first error is statistical and the second is systematic. The q2 distribution is compared to theoretical predictions based on quark model and light cone sum rule form factor calculations11ocn082064919book1998Quinn, Helen RThe asymmetry between matter and antimatter11ocn819774967art19980.47Quinn, Helen RAsimetria entre materia y antimateria11ocn311622744visu20080.47Quinn, Helen RThe mystery of the missing antimatterDr. Helen Quinn of the Stanford Linear Accelerator Center tells how physicists address the puzzle of how it came about that, with very similar laws of physics for matter and antimatter, the Universe is populated with matter but very little antimatter+-+8458866415+-+8458866415Fri Mar 21 15:16:51 EDT 2014batch11116
