Status and perspectives of sin2alpha measurements
H. Sagawa
Abstract
In the neutral B meson system, it is possible to measure the CKM angle alpha using the decay mode b -> u ubar d in the presence of pollution from gluonic b -> d penguin decays. Here the recent status of the measurements of CP-violating asymmetry parameters using time-dependent analyses in B -> pi+pi- and B -> rho pi decays and the perspectives of a sin2alpha measurement are presented.
