Theoretical Studies in Elementary Particle Physics

这个项目强调在当前和未来的加速器实验中测试理论想法的方法的发展。该项目的第一部分涉及目前的问题，涉及非常成功和不可或缺的“基于QCD的部分子模型”--部分子分布函数的“小x”行为，它支配着所有未来加速器，包括超导超级对撞机(SSC)预期的事件速率；以及计算由重夸克部件引发的新粒子产生的方法。我们将详细研究希格斯粒子的产生，它负责规范对称性的自发破缺。该项目的第二部分涉及W矢量玻色子和Z矢量玻色子的物理，它们协调统一的电弱相互作用。到目前为止，这些规范玻色子的三波色子耦合的实验后果将被深入探索，并着眼于在高能电子-正电子对撞机SLC和LEP上进行尖锐的测试。我们将研究虚拟W和Z的效应，特别是高能过程的“有效矢量玻色子”近似。这项工作的结果应该特别有助于确保拟议的超导超导对撞机加速器的最大有效性，除了增加我们对标准(Salaam-Weinberg)电弱过程模型的全面影响的一般知识。

This project emphasizes development of methods to test theoretical ideas in current and future accelerator experiments. The first part of the project deals with current problems concerning the very successful and indispensable "QCD- based parton model" - the "small-x" behavior of the parton distribution functions which governs the rates of events expected at all future accelerators, including the Superconducting Super Collider (SSC); and methods of calculating the production of new particles initiated by heavy quark-partons. The production of the Higgs particle which is responsible for the spontaneous breaking of gauge symmetries will be studied in detail. The second part of the project concerns the physics of the W and Z vector bosons which mediate the unified electro-weak interactions. Experimental consequences of the hitherto unverified tri-boson coupling of these gauge bosons will be explored in depth with an eye for incisive tests at the high-energy electron-positron colliders SLC and LEP. Effects due to virtual W's and Z's, especially the "effective vector boson" approximation to high energy processes, will be studied. The results of this work should help specifically to ensure maximum effectiveness of the proposed superconducting supercollider accelerator, in addition to increasing our general knowledge of the full implications of the Standard (Salaam-Weinberg) Model of electroweak processes.
