Measurement of the CP-Violation Parameter sin2 phi(1) with a New Tagging Method at the gamma(5S) Resonance

Jean Wicht, Remi Léandre Albert Louvot, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Jun Yong Kim, Ji Hyun Kim, Yiming Li, Xiao Wang, Jing Li

We report a measurement of the CP-violation parameter sin2 phi(1) at the gamma(5S) resonance using a new tagging method, called "B-pi tagging." In gamma(5S) decays containing a neutral B meson, a charged B, and a charged pion, the neutral B is reconstructe ...
