Renormalisation group invariants and sum rules: fast diagnostic tools for probing high-scale physics

摘要

A method is described to probe high-scale physics in lower-energy experimentsby employing sum rules in terms of renormalisation group invariants. The methodis worked out in detail for the study of supersymmetry-breaking mechanisms inthe context of the Minimal Supersymmetric Standard Model. To this end sum rulesare constructed that test either specific models of supersymmetry breaking orgeneral properties of the physics that underlies supersymmetry breaking, suchas unifications and flavour-universality.
