Static cavity calculation of heavy meson neutral mixing with QCD corrections

Description

The neutral mixing matrix elements describing D deg and B deg mixing are calculated in a static cavity model previously fitted to the ΔI=1/2 rule of kaon decay. Since the model is based on O(g) wavefunctions, computation of hadronic matrix elements includes O(g2) corrections. Specifically, the quantities fD√BD and FB√BB were computed for basis sizes NB=1,2,3 and 6. At NB=6, the values FD√BD =90 MeV and FB√BB=62 MeV. The ratio of these quantities agrees well with non-relativistic expectations. 8 refs., 2 figs
