- W2251528079 abstract "In a wide class of NP models, which can be motivated through generic arguments and within SUSY, we obtain large contributions to $B^0_d$--$bar B^0_d$ mixing, but not to $Delta B=1$ processes. If we assume such a scenario, the solutions $phi_dsim 47^circlor 133^circ$ for the $B^0_d$--$bar B^0_d$ mixing phase implied by $A_{CP}^{mix}(B_dto J/psi K_S)$ cannot be converted directly into a constraint in the $rho$--$eta$ plane. However, we may complement $phi_d$ with $|V_{ub}/V_{cb}|$ and the recently measured CP asymmetries in $B_dtopi^+ pi^-$ to determine the unitarity triangle, with its angles $alpha$, $beta$ and $gamma$. To this end, we have also to control penguin effects, which we do by means of the $B_dtopi^mp K^pm$ branching ratio. Interestingly, the present data show a perfectly consistent picture not only for the ``standard'' solution of $phi_dsim 47^circ$, but also for $phi_dsim 133^circ$. In the latter case, the preferred region for the apex of the unitarity triangle is in the second quadrant, allowing us to accommodate conveniently $gamma>90^circ$, which is also favoured by other non-leptonic B decays such as $Btopi K$. Moreover, also the prediction for BR$(K^+topi^+nubarnu})$ can be brought to better agreement with experiment. Further strategies to explore this scenario with the help of $B_{d,s}tomu^+mu^-$ decays are discussed as well." @default.
