Soft Spectrum in Yukawa-Gauge Mediation
Federico Galli, Alberto Mariotti
TL;DR
This paper introduces a new formalism called Yukawa-gauge mediation for gauge mediated theories, providing general formulas for soft masses and revealing conditions where gaugino masses are suppressed.
Contribution
It develops a model-independent parametrization for Yukawa-gauge mediation and derives expressions showing gaugino mass screening under generic conditions.
Findings
Gaugino masses are screened and vanish at first order in SUSY breaking scale.
Provides general formulas for gaugino and scalar masses in Yukawa-gauge mediation.
Formalism applies broadly to a subclass of gauge mediated theories.
Abstract
We introduce a model independent parametrization for a subclass of gauge mediated theories, which we refer to as Yukawa-gauge mediation. Within this formalism we study the resulting soft masses in the visible spectrum. We find general expressions for the gaugino and scalar masses. Under generic conditions, the gaugino mass is screened, vanishing at first order in the SUSY breaking scale.
