Abstract

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.
