Abstract / 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
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. 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
m_h are not significant for moderate generation mixing.
