Physics with Polarized Z's

这是罗格斯大学物理系的两名教师提出的一项建议，他们将继续研究使用SLD探测器和SLAC的线性电子对撞机分析极化Z衰变。 加速器已经实现了62%的电子束极化，并计划在未来几年内收集1，000，000个Z衰变。 这将使SLD小组能够通过一种与LEP不同的技术，对温伯格角进行世界上最精确的测量。 两个加速器测量值之间的差异将是标准模型中辐射修正的重要度量。 Z的偏振也将使他们能够对Bs的混合进行重要的测量。 罗格斯大学的小组一直在安装端盖CRID（切伦科夫环成像探测器），他们现在正在从事其校准和改进的跟踪，这是必要的使用CRID的颗粒识别。

This is a proposal from two members of the faculty in the physics department at Rutgers to continue their research in the analysis of polarized Z decays using the SLD detector and the linear electron collider at SLAC. The accelerator has achieved a 62% polarization of the electron beam and the stated plan is to collect 1,000,000 Z decays over the next several years. This will allow the SLD group to make what is expected to be the world's most accurate measurement of the Weinberg Angle by a technique which is different from that at LEP. The difference between the measurements at the two accelerators will be an important measure of the radiative corrections in the standard model. The polarization of the Z will also allow them to make significant measurements of Bs mixing. The Rutgers group has been instrumental in the installation of the END CAP CRID (Cerenkov Ring Imaging Detector) and they are now engaged in its calibration and in the improvements to the tracking which are necessary to use the CRID for particle identification.
