Abstract

Measurements of Flavor Changing Neutral Current (FCNC) processes (rare decays, flavor mixing) play a key role to pursue new physics beyond the Standard Model. We present recent analysis results about some FCNC transitions performed by CDF and D0 collaborations, including the first observation of the B_s->phi mu^+mu^- mode, the forward-backward asymmetry measurement in B->K^(*) mu^+mu^-, and updated measurements of B_s (B^0)->mu^+mu^-, using data corresponding to integrated luminosities from 3.7/fb to 5/fb. We also show the CDF/D0 combined measurement of the B_s mixing phase using 2.8/fb of data per experiment.
