RECENT RESULTS ON CP VIOLATION IN B DECAY

Abstract

This paper, 40 years after the discovery of CP violation 1 in neutral kaon decay in the famous experiment of Brookhaven, presents the most recent results on the CP violation in the b sector as come out of the experiments BABAR and BELLE that are taking data since 1999 at PEPII and KEKB e+e- asymmetric B -Factories operating at the center of mass energy corresponding to the mass of the ϒ4S. After their initial discovery of the CP violation and the measurement of sin2β in 2001 2, now is the time of the observation of direct CP violation by BABAR, confirmed by BELLE, the initial measurements of α, the first clue of γ and the very intriguing results about the measurements of sin2β in the time dependent analysis of decay channels via penguin loops, where [Formula: see text] and [Formula: see text].
