Physics with Polarized Z's

这是罗格斯大学物理系的两名教员提出的一项建议，他们将继续使用SLD探测器和SLAC的线性电子对撞机分析极化Z衰变的研究。加速器已经实现了62%的电子束极化，所述的计划是在未来几年收集100万个Z衰变。这将使SLD团队能够使用一种不同于LEP的技术来测量温伯格角，预计将是世界上最准确的测量。两个加速器的测量结果之间的差异将是标准模型中辐射校正的一个重要量度。Z的极化也将使他们能够对BS混合进行重要的测量。罗格斯小组在安装End CAP CRID(切伦科夫环成像探测器)方面发挥了重要作用，他们现在正在进行校准和改进跟踪，这是使用CRID进行颗粒识别所必需的。

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.
