Constraints on New Physics from gamma and |V_ub|

Abstract

The SM unitarity triangle (UT) is completely determined by the parameters $\gamma$ and $|V_{ub}|$ which can be extracted from tree-level processes and are assumed to be free of new physics. By comparison with other determinations of UT parameters one can impose constraints on new physics in loop processes, in particular $B$ mixing.
