Abstract
CP violation (CPV), first detected in K L → π + π − decays in 1964 [1], is accomodated in the Standard Model (SM) by a CP-violating phase in the CKM matrix, the matrix which describes the mixing of the quarks (under the weak interaction) [2]. From the unitarity constraints of the CKM matrix, we have V ud V *ub + V cd V *cb + V td V *tb = 0, the so-called Unitarity Triangle relation, represented in Fig. 1. CPV is proportional to the area of the triangle and requires the angles and sides to be different from zero. The main goal of the BaBar experiment [3] is to overconstrain the Unitarity Triangle parameters, measuring the sides and the angles directly from the data of B u and B d meson decays, in order to test the consistency of the SM.
