26 Oct 2004 | | Journal: | Phys.Rev. D71 (2005) 054014 | | Subject: | hep-ph | | Affiliation: | Yonsei U.), Yeong Gyun Kim (Korea U.), and Kang Young Lee (KAIST | | Abstract: | Since the CP violation in the $B$ system has been investigated up to now only through processes related to the $B$--$ar{B}$ mixing, urgently required is new way of study for the CP violation and establishing its origin in the $B$ system independent of the mixing process. In this work, we explore the exclusive $ B^0 o
ho^0 gamma$ decay to obtain the time-dependent CP asymmetry in $b o d$ decay process in the standard model and the supersymmetric model. We find that the complex RL and RR mass insertion to the squark sector in the MSSM can lead to a large CP asymmetry in $b o d gamma$ decay through the gluino-squark diagrams, which is not predicted in the Standard Model induced by the $B$--$ar{B}$ mixing. | | Source: | arXiv, hep-ph/0410343 | | Services: | Forum | Review | PDF | Favorites | |
