The Effect of Slepton Flavor Mixing on the Mass of SM-like Higgs Boson in the MSSM

We investigate the one-loop contributions to the mass of the SM-like Higgs boson in the MSSM considering the effect of slepton flavor mixing, which is parametrized by the dimensionless parameter δXY (X, Y = L, R) in the slepton mass matrices. For the surviving samples under the experimental constraints, we calculate the corrections to the mass of the SM-like Higgs boson in terms of δXY. We find that the mass correction Δmh can even be larger than 10 GeV for large δRL or δLR. Moreover, Δmh has strong sensitivity to δRL or δLR, while the weak sensitivity to δLL or δRR, since δRL or δLR enters directly into the coupling of Higgs boson with sleptons in the calculations of Higgs boson self-energies.
