B - phi OKs versus electric dipole moment of Hg-199 atom in supersymmetric models with right-handed squark mixing

摘要

The correlation between the CP asymmetry in B --> (S-phiKs) and the chromoelectric dipole moment (CEDM) of strange quark (d(s)(C)), which is constrained by the electric dipole moment (EDM) of Hg-199, is studied in the supersymmetric (SUSY) models with the right-handed squark mixing. It is known that, if the right-handed bottom and strange squarks have a CP-violating mixing, such as in the SUSY SU(5) GUT with right-handed neutrinos, the induced gluon penguin diagram may give a sizable contribution to S-phiKs. However, when the left-handed bottom and strange squarks also have a mixing, the conspiracy of the left and right-handed squarks may lead to a sizable d(s)(C), which is enhanced by m(b)/m(s). While the estimate for the EDM of Hg-199, induced by d(s)(C), might have large uncertainties due to the hadron and nuclear dynamics, the current bound implies the gluon penguin contribution by the right-handed squarks to S-phiKs should be suppressed and the deviation Of S-phiKs from the Standard Model may not be so large. Also, we discuss the constraint from the EDM of 199Hg in the SUSY SU(5) GUT with the right-handed neutrinos. (C) 2004 Published by Elsevier B.V. References: 19
