In the current version of this work we consider the first direct experimental bound on the mass difference Delta mB_s recently reported by DO along with the first measurement achieved by CDF, Delta mB_s=(17.33 + - 0.4) ps^{-1}. In particular we show how these measurements further constrain the compatibility between the experimental value of sin(2beta)^{exp.}=(0.591,0.783) at 99% C.L. and the value obtained by the fit of the CKM parameters considering just CP conserving experimental observables: sin(2beta)^{CP-conserv.}=(0.742,0.856) at 99% C.L. We also obtain bounds on certain classes of processes beyond the SM.Updated version after the first Delta mB_s measurement.
