Electroweak precision observables in the MSSM with nonminimal flavor violation

The leading corrections to electroweak precision observables in the MSSM with non-minimal flavor violation (NMFV) are calculated and the effects on M_W and sin^2 \theta_{eff} are analyzed. The corrections are obtained by evaluating the leading one-loop contributions to the quantity \Delta \rho, incl...

description The leading corrections to electroweak precision observables in the MSSM with non-minimal flavor violation (NMFV) are calculated and the effects on M_W and sin^2 \theta_{eff} are analyzed. The corrections are obtained by evaluating the leading one-loop contributions to the quantity \Delta \rho, including the mixing in the scalar top and charm, as well as in the scalar bottom and strange sector. Furthermore the leading corrections to the mass of the lightest MSSM Higgs boson, mh, is obtained. The electroweak one-loop contribution to M_W can amount up to 140 MeV and up to 70x10^{-5} for sin^2 \theta_{eff}, allowing to set limits on the NMFV parameters. The corrections for mh are not significant for moderate generation mixing.

The corrections are obtained by evaluating the full one-loop contributions from the third and second generation scalar quarks, including the mixing in the scalar top and charm, as well as in the scalar bottom and strange sector. Furthermore the leading corrections to the mass of the lightest MSSM Higgs boson, m_h, is obtained.
