The status of the unitary triangle beyond the standard model including the most recent results on Delta m(s) on dilepton asymmetries and on width differences is presented. Even allowing for general new physics loop contributions the unitarity triangle must be very close to the standard model result. With the new measurements from the Fermilab Tevatron, we obtain for the first time a significant constraint on new physics in the B-s sector. We present the allowed ranges of new physics contributions to Delta F=2 processes and of the time-dependent CP asymmetry in B-s -> J/psi phi decays.
