Experimental review on the Unitarity Triangle angles $\alpha$(φ2) and $\beta$(φ1)
2017 January 12
The precise determination of the angles of the Unitarity Triangle can put tight constraints on the flavor sector of the Standard Model, by probing the validity of the Cabibbo-Kobayashi-Maskawa scheme. The measurement of time-dependent CP asymmetries provides the main experimental means to determine the angles alpha and beta. The present status of the knowledge of these two angles and a summary of recent measurements performed by the BABAR, Belle and LHCb experiments are reported in this proceedings article.
