Modified Higgs Boson Phenomenology from Gauge or Gaugino Mediation in the NMSSM

Understand

In the Next-to-Minimal Supersymmetric Standard Model (NMSSM), the presence of light pseudoscalars can have a dramatic effect on the decays of the Standard Model-like Higgs boson.

• These pseudoscalars are naturally light if supersymmetry breaking preserves an approximate U(1)_R symmetry, spontaneously broken when the Higgs bosons take on their expectation values.
• We investigate two classes of theories that possess such an approximate U(1)_R at the mediation scale: deformations of gauge and gaugino mediation.
• In the models we consider, we find two disjoint classes of phenomenologically allowed parameter regions.
