abstract = {Within the Constrained Minimal Supersymmetric
Standard Model (CMSSM) with Minimal Flavor Violation
(MFV) for scalar quarks, we study numerically the
effects of intergenerational squark mixing on B-physics
observables, electroweak precision observables (EWPO),
and the Higgs-boson mass predictions. In models with universal
soft terms at theGUTscale, squarkmixing is generated
through the Renormalization Group Equations (RGEs) running
from theGUTscale to the electroweak scale due to presence
of non-diagonal Yukawa matrices in the RGEs, e.g. due
to the CKM matrix. Our numerical analysis is based on the
code Spheno for the RGE running and full one-loop calculations,
supplemented by further higher-order corrections, at
the electroweak scale of the precision observables as included
in the code FeynHiggs. Taking the CMSSM as a concrete
“realistic” example, we find that the B-physics observables
as well as the Higgs mass predictions do not receive sizable
corrections. On the other hand, in our numerical analysis we
observe that the EWPOsuch as theW boson mass can receive
relevant corrections. Such contributions could in principle be
used to place new bounds on the CMSSM parameter space.
We extend our numerical analysis to the CMSSM extended
with a mechanism to explain neutrino masses (CMSSMseesaw
I), which induces flavor violation in the scalar lepton
sector. The effects of slepton mixing on the analyzed observables
are found to be, in general, smaller than those of squark
mixing, but in our numerical analysis reach the level of the
current experimental uncertainty for the EWPO.},
