Sflavor mixing map viewed from a high scale in supersymmetric SU(5)

Understand

We study flavor violation in a supersymmetric SU(5) grand unification scenario in a model-independent way employing mass insertions.

• We examine how the quark and the lepton sector observables restrict sfermion mixings.
• With a low soft scalar mass, a lepton flavor violating process provides a stringent constraint on the flavor structure of right-handed down-type squarks.
• In particular, mu -> e gamma turns out to be highly susceptible to the 1-3 and 2-3 mixings thereof, due to the radiative correction from the top Yukawa coupling to the scalar mass terms of 10.
