A study of the static-light BB parameter

Joseph Christensen, Terrence Draper, Craig McNeile

Research output: Contribution to journalArticlepeer-review


We calculate the BB parameter, relevant for B0-B0 mixing, from a lattice gauge theory simulation using the static approximation for the heavy quark and the Wilson action for the light quark and gauge fields. Improved sources, produced by an optimized variational technique, MOST, reduce statistical errors and minimize excited-state contamination of the ground-state signal. Renormalization of four-fermion operator coefficients, using the Lepage-Mackenzie procedure for estimating typical momentum scales, is linearized to reduce order α2s uncertainties.
