Our wall as the origin of CP violation
arXiv:hep-th/0011098 · doi:10.1016/S0550-3213(01)00277-2
Abstract
A possibility that the origin of the CP violation in our world is a domain wall itself, on which we are living, is investigated in the context of the brane world scenario. We estimate the amount of the CP violation on our wall, and show that either of order one or suppressed CP phases can be realized. An interesting case where CP is violated due to the {\it coexistence} of the walls, which conserve CP individually, is also considered. We also propose a useful approximation for the estimation of the CP violation in the double-wall background.
