Measurement of sin2beta in tree-dominated B0-decays and ambiguity removal

High Energy Physics - Experiment 2015-06-25 v1

Abstract

The most recent results from the B-factories on the time-dependent CP asymmetries measured in B0-decays mediated by b --> c c(bar) s quark-transitions are reviewed. The Standard Model interpretation of the results in terms of the parameter sin2beta leads to a four-fold ambiguity on the unitarity triangle beta which can be reduced to a two-fold ambiguity by measuring the sign of the parameter cos2beta. The results on cos2beta obtained so far are reviewed.
