Abstract: (arXiv)

We confirm that in order to account for the recent D\O\ result of large like-sign dimuon charge asymmetry, a considerable large new physics effect in

\Gamma_{12}^s

is required in addition to a large CP violating phase in

B_s -\bar{B}_s

mixing. In the Randall-Sundrum model of warped geometry, where the fermion fields reside in the bulk, new sources of flavor and CP violation are obtained. We analyze the like-sign dimuon asymmetry in this class of model, as an example of the desired new physics. We show that the wrong charge asymmetry,

a_{sl}^s

, which is related to the dimuon asymmetry, is significantly altered compared to the Standard Model value. However, experimental limits from

\Delta M_s

,

\Delta\Gamma_s

as well as

K

mixing and electroweak corrections constrain it to be greater than a

\sigma

away from its experimental average value. This model cannot fully account for the D\O\ anomaly due to its inability to generate sufficient new contribution to the width difference

\Gamma^s_{12}

, even though the model can generate large contribution to the mass difference

M^s_{12}

.
