Findings

NMFV relaxes constraints on GMSB parameter space.

Benchmark scenarios for LHC sparticle production are proposed.

Numerical predictions for cross sections are provided.

Abstract

We present an extensive analysis of low-energy, electroweak precision, and cosmological constraints in the Minimal Supersymmetric Standard Model (MSSM) with Gauge-Mediated Supersymmetry Breaking (GMSB) and including the possibility of Non-Minimal Flavour Violation (NMFV). Using detailed scans over the parameter space, we show how NMFV allows to relax the stringent constraints excluding large parts of the minimal GMSB. We define benchmark scenarios and present numerical predictions for various sparticle production cross sections at the LHC.
