<f>Bd</f>–<f><ovl type="bar" STYLE="S">B</ovl>d</f> mixing and the <f>Bd→J/ψKs</f> asymmetry in general SUSY models

We present a next-to-leading order determination of the gluino-mediated SUSY contributions to <f>Bd</f>–<f><ovl type="bar" STYLE="S">B</ovl>d</f> mixing and to the CP asymmetry <f>aJ/ψKs</f> 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. [Copyright &y& Elsevier]
