Remark on the theoretical uncertainty in B0-Bbar0 Mixing

PDF Version Also Available for Download.

Description

The authors re-examine the theoretical uncertainty in the Standard Model expression for B{sup 0}-{bar B}{sup 0} mixing. They focus on lattice calculations of the ratio {xi}, needed to relate the oscillation frequency of B{sub s}{sup 0}-{bar B}{sub s}{sup 0} mixing to V{sub td}. They replace the usual linear chiral extrapolation with one that includes the logarithm that appears in chiral perturbation theory. We find a significant shift in the ratio {xi}, from the conventional 1.15 {+-} 0.05 to {xi} = 1.32 {+-} 0.10.
