Conclusions

We found bounds for flavor from B physics, and large corrections to the Higgs boson masses compatible with these bounds, up to several tens GeV for the lightest boson.

These corrections are two orders of magnitude larger than the LHC precission, and three orders than the ILC.

Mainly coming from the ct sector (which is less constrained by B- Physics) and from scenarios with low . Also from high if SUSY is very heavy (order 1 TeV or larger).

These corrections can be used to set further bounds on flavour
