Summary
Abstract:
We investigate the effect of the dimuon CP asymmetry from
the B decay modes, recently observed at 3.2 sigma deviation
from the Standard Model (SM) by the D0 collaboration, in
order to probe new physics. To obtain the large dimuon CP
asymmetry, the dispersive and absorptive parts of mixing
amplitudes. A large amount of flavor violation between the
second and the third generation is generated due to the
large neutrino atmospheric mixing angle and this flavor
violation can be responsible for the large CP asymmetry in
grand unified theories. We exhibit the GUT scenarios and the
constraints from the other flavor violating processes. We
also study the modification of the absorptive part of the
mixing amplitude.
