摘要:

The results of high precision weak neutral current (WNC),Z‐pole, and high energy collider electroweak experiments have been the primary prediction and test of electroweak unification. The electroweak program is briefly reviewed from a historical perspective. Current changes, anomalies, and things to watch are summarized, and the implications for the standard model and beyond discussed. © 2004 American Institute of Physics

摘要:

From the famous experiments of Stern and Gerlach to the present, measurements of magnetic dipole moments, and searches for electric dipole moments of “elementary” particles have played a major role in our understanding of sub‐atomic physics. In this talk I discuss the progress on measurements and theory of the magnetic dipole moments of the electron and muon. I also discuss a new proposal to search for a permanent electric dipole moment (EDM) of the muon and put it into the more general context of other EDM searches. © 2004 American Institute of Physics

摘要:

Electron Scattering from nucleons and light mesons has provides precise information about the ground state structure of matter. In this talk I present a survey of recent experimental progress on the electromagnetic and weak structure of nucleons as well as the structure of pions and kaons. © 2004 American Institute of Physics

摘要:

In this talk I discuss recent advances in Quantum Chromo‐Dynamics, in particular the progress in understanding the collective dynamics of the theory. I emphasise the significance of the RHIC program for establishing the properties of hot and dense QCD matter and for understanding the dynamics of the theory at the high parton density, strong color field frontier. Hopes and expectations for the future are discussed as well. © 2004 American Institute of Physics

摘要:

My presentation will focus on some of the latest results of the neutron spin physics program at Jefferson Laboratory in Hall A using a polarized3He target. This program includes several completed experiments in which the spin structure functions of3He were measured. The covered kinematic regions were these measurements were performed include the lowQ2resonance and inelastic regions and the highQ2deep inelastic region. These experiments offer a ground for testing our understanding of the strong regime of quantum chromodynamics (QCD) through the determination of the neutron spin‐dependent structure functions and their moments. © 2004 American Institute of Physics

摘要:

Experiment E158 has recently observed parity violation in the scattering of polarized electrons from the electrons in a liquid hydrogen target at SLAC. The results are consistent with the predictions of the Standard Model. We plan to obtain additional data by the end of the summer of 2003 to provide the most precise measurement of sin2&thgr;Wat low energy. © 2004 American Institute of Physics

摘要:

I discuss the theoretical implications of the WMAP results, stressing WMAP’s detection of a correlation between the E‐mode polarization and temperature anisotropies, which provides strong support for the overall inflationary paradigm. I point out that almost all inflationary models have a “vanilla limit,” where their parameters cannot be distinguished from a genuinely de Sitter inflationary phase. Because its findings are consistent with vanilla inflation, WMAP cannot exclude entire classes of inflationary models. Finally, I summarize hints in the current dataset that the CMB contains relics of new physics, and the possibility that we can use observational data to reconstruct the inflaton potential. © 2004 American Institute of Physics

摘要:

The KLOE experiment at DA&Fgr;NE collected about 450 pb−1of data in 2001–2002. Much of this data set has been analyzed and has yielded definitive results onKSand radiative &fgr; decays, as well as studies concerning a wide range of topics in kaon and hadronic physics. © 2004 American Institute of Physics
