Investigations in High Energy Physics

本提案将涉及实现用轻动力学夸克模拟完全未淬晶格QCD的新算法。一种方法是使用新的截断行列式和多玻色子算法。这种方法精确地处理了红外夸克模式。计算将在163 x 32的格子上完成。本文将探讨在电磁强子精细结构的非淬灭研究中使用全点传播子的可行性。将对最近在Tevatron上发现的Bc介子的衰变进行详细的研究。恢复技术将用于研究标准模型和非标准模型粒子的辐射衰减和产生过程。解构理论和超维理论的高能行为之间的差异将被研究。

This proposal will be concerned with implementing new algorithms for doing simulations of fully unquenched lattice QCD with light dynamical quarks. One approach will be the use of a new truncated determinant and multi-boson algorithm. In this approach the infrared quark modes are treated exactly. Calculations will be done on a 163 x 32 lattice. The feasibility of using all-point propagators in an unquenched study of electromagnetic hadronic fine-structure will be examined. A detailed study will be made of the decays of the Bc Meson, which was recently seen at the Tevatron. Resummation techniques will be used in studying the radiative decays as well as production processes of Standard Model and beyond the standard model particles. Differences between the high energy behavior of deconstructed theories and extra-dimension theories will be investigated.
