Bd-Bbard Mixing and the Bd -> J/psi Ks Asymmetry in General SUSY Models
Abstract
We present a next-to-leading order determination of the gluino-mediated SUSY contributions to Bd-Bbard mixing and to the CP asymmetry aJ/psi Ks in the framework of the mass-insertion approximation. Using hadronic matrix elements recently computed on the lattice, we obtain improved constraints on the squark-mass splittings.
