Proton-Proton and Proton-Antiproton Collision Beam Physics at CERN and the SSC

该奖项将为加州大学洛杉矶分校的一个小组继续高能物理研究提供支持。该小组的目的是研究使用强子对撞机作为B介子的强源(B工厂)的可能性，以研究它们的性质。为此，加州大学洛杉矶分校的团队正计划在欧洲核子研究中心(CERN)的超质子同步加速器(SPS)上测试一种新的探测器。探测器的几何结构利用了这样一个事实，即高能B介子的产生在正反方向上达到峰值。B介子的探测是用大口径正向光谱仪和硅微顶探测器作为触发器完成的。还提出了新的触发思想，其中所有信息都来自对来自硅微顶点探测器的数据的实时处理。这种硅触发器将在SPS对撞机上进行测试。加州大学洛杉矶分校的研究小组还在继续分析CERN SPS对撞机上UA8实验的数据，在该对撞机中，为了研究波美子的内部结构，测量了含有领先质子的事件中粒子喷射的测量结果。

This award will provide support to a group from the University of California, Los Angeles to continue research in high energy physics. The aim of the group is to study the possibility of using hadron colliders as intense source of B mesons (B factory) for the study of their properties. For this the UCLA group is planning a test run of a new detector at the Super Proton Synchrotron (SPS) at CERN (Switzerland). The geometry of the detector uses the fact that the production of B mesons at high energy peaks in the forward backward direction. The detection of B mesons is done with a large aperture forward spectrometer and with a silicon microvertex detector as trigger. New triggering ideas are also proposed in which all information is derived from real time processing of data from the silicon microvertex detector. This silicon trigger will be tested in a run at the SPS collider. The UCLA group is also continuing the analysis of data from experiment UA8 at the CERN SPS collider in which the measurement of jets of particles, in events which contain leading protons, are measured in order to study the internal structure of the Pomeron.
