$M_{W}, \sin^{2} \theta_{eff}$ and $m_{h}$ in the NMFV MSSM

The effects of loop contributions to the electroweak precision observables and m_h in the MSSM with non-minimal flavour violation (NMFV) are analyzed, including the mixing between third and second generation squarks. The mixing-induced shift in M_W can amount to 140 MeV and to 70x10^{-5} in sin^2 \t...

description The effects of loop contributions to the electroweak precision observables and m_h in the MSSM with non-minimal flavour violation (NMFV) are analyzed, including the mixing between third and second generation squarks. The mixing-induced shift in M_W can amount to 140 MeV and to 70x10^{-5} in sin^2 \theta_{eff} for extreme values of squarks mixing, allowing to set limits on the NMFV parameters. The corrections for m_h are usually small and can amount up to O(5 GeV) for large flavour violation.
