 Title: Determination of the Neutral B Meson and Neutral B(s) Meson Mixing Matrix Elements in 2+1 Lattice QCD Author(s): Evans, Richard Doctoral Committee Chair(s): El-Khadra, Aida X Department / Program: Physics Discipline: Physics Degree Granting Institution: University of Illinois at Urbana-Champaign Degree: Ph.D. Genre: Dissertation Subject(s): Physics, Elementary Particles and High Energy Abstract: This report presents a calculation and results for the matrix elements relevant for the analysis of B0 -- B¯0 mixing using the Asqtad (light-quark) and Fermilab (heavy-quark) actions. The calculation is performed on the 2+1 MILC ensembles at three different lattice spacings, and uses staggered chiral perturbation theory to perform the extrapolations to the physical light quark masses as well as to the continuum. All known systematic errors are explored and estimated resulting in a value and uncertainty for xi that can be used directly as input for Unitarity constraints.
