Squark Mixing Contributions to CP violating phase gamma
We investigate the possibility that the CP violation due to the soft
supersymmetry breaking terms in squark mixing can give significant
contributions to the various related parameters in B decays, different
from those of the Standard Model. We derive the new limits on
and on from the
recent data on -- oscillation as well as those on
-- oscillation. We show that, together with all the other
constraints, the currents limits on these parameters still allow large
contributions to the CP violating phases in -- as well as
-- oscillations which will modify some of the proposed
measurements of parameters in CP violating B decays. However, the
current constraints already dictate that the one-loop squark mixing
contributions to various B decay amplitudes cannot be competitive with that of
the Standard Model (SM), at least for those B decay modes which are dominated
the tree level amplitudes within the SM, and therefore they are not significant
in contributing to CP asymmetries in the corresponding B decays.Comment: 15 page
