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.

该提案将与实施新算法有关使用轻型动态夸克进行完全无震动的晶格QCD进行模拟。一种方法将是使用新的截短的决定因素和多个玻色子算法。在这种方法中，精确处理红外夸克模式。计算将在163 x 32晶格上完成。将检查在无震动的电磁辐射细胞结构研究中使用全点传播器的可行性。将对BC介子的衰减进行详细研究，该研究最近在Tevatron上看到。 重新召集技术将用于研究辐射衰变以及标准模型和标准模型颗粒之外的生产过程。将研究解构理论的高能量行为与超维理论之间的差异。
