Speaker: Christopher Aubin (W&M) Title: B_K (and more!) Using Chiral Perturbation Theory and the Lattice Abstract: In recent years numerous calculations have made use of both advancing computer power and algorithms in order to obtain precise results using lattice QCD. I will primarily discuss a set of calculations using a "mixed-action" approach, the final goal of which is a determination of B_K, the neutral kaon bag parameter. If there is time, I will also discuss other quantities of relevance to hadronic physics that are also able to make a strong impact soon in the community.
