Investigations in High Energy Physics

这项提议将致力于实现新的算法来模拟具有轻动力学夸克的完全非猝灭的晶格QCD。一种方法是使用一种新的截断行列式和多玻色子算法。在这种方法中，红外夸克模得到了精确的处理。计算将在163x32的晶格上进行。我们将研究在电磁强子精细结构的非猝灭研究中使用全点传播子的可行性。将对BC介子的衰变进行详细的研究，这是最近在泰瓦顿看到的。再融合技术将被用于研究标准模型粒子的辐射衰变和产生过程以及标准模型粒子以外的粒子。我们将研究解构理论和超维理论的高能行为之间的差异。

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.
