Contribution
It offers new insights and alternative derivations of anomaly mediation formulas, highlighting its universality beyond supergravity and supersymmetry breaking.
Findings
Anomaly mediation is a familiar quantum field theory phenomenon.
The phenomenon occurs independently of supersymmetry breaking.
Multiple derivations of gaugino and scalar mass formulas are provided.
Abstract
We elucidate the physics underlying ``anomaly mediation'', giving several alternative derivations of the formulas for gaugino and scalar masses. We stress that this phenomenon is of a type familiar in field theory, and does not represent an anomaly, nor does it depend on supersymmetry breaking and its mediation. Analogous phenomena are common in QFT and this particular phenomenon occurs also in supersymmetric theories without gravity.
