B(s)-B(s)bar Mixing in Grand Unified Models | | Bhaskar Dutta

12 Jul 2006 | | Abstract: | We study B_s-ar{B}_s mixing in grand unified SO(10), SU(5) models where the mixings among the second and third generation squarks arise due to the existence of flavor violating sources in the Dirac and Majorana couplings which are responsible for neutrino mixings. We find that when the branching ratio of tau->mu gamma decay is enhanced to be around the current experimental bound, B_s-ar{B}_s mixing may also contain large contribution from supersymmetry in the SO(10) boundary condition. Consequently, the phase of B_s-ar{B}_s mixing is large (especially for small tan beta and large scalar mass m_0) and can be tested by measuring CP asymmetries of B_s decay modes. | | Source: | arXiv, hep-ph/0607147 | | Services: | Forum | Review | PDF | Favorites | |
