B_d-Bbar_d Mixing and the B_d -> J/psi K_s Asymmetry in General SUSY Models

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/178946We present a next-to-leading order determination of the gluino-mediated SUSY contributions to B_d-Bbar_d mixing and to the CP asymmetry a_{J/psi K_s} 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.17 pages, 13 figuresHigh Energy Physics - PhenomenologyB_d-Bbar_d Mixing and the B_d -> J/psi K_s Asymmetry in General SUSY Modelstext
