750 GeV Diphoton Resonance, 125 GeV Higgs and Muon g-2 Anomaly in Deflected Anomaly Mediation SUSY Breaking Scenario

TL;DR

This paper explores a supersymmetry breaking scenario that can simultaneously explain the 750 GeV diphoton excess, the 125 GeV Higgs, and the muon g-2 anomaly, aligning with experimental constraints.

Contribution

It introduces a deflected anomaly mediation SUSY breaking model that naturally links a singlet scalar to the diphoton resonance and addresses multiple experimental anomalies.

Findings

The model can produce a 750 GeV scalar resonance compatible with diphoton excess.

It successfully accounts for the 125 GeV Higgs boson.

The scenario explains the muon g-2 anomaly without conflicting with LHC data.

Abstract

We propose to interpret the 750 GeV diphoton excess in deflected anomaly mediation supersymmetry breaking scenarios, which can naturally predict couplings between a singlet field and vector-like messengers. The CP-even scalar component (S) of the singlet field can serve as the 750 GeV resonance. The messenger scale, which is of order the gravitino scale, can be as light as F_\phi \sim {\cal O}(10) TeV when the messenger species N_F and the deflection parameter d are moderately large. Such messengers can induce the large loop decay process S \to \gamma\gamma. Our results show that such a scenario can successfully accommodate the 125 GeV Higgs boson, the 750 GeV diphoton excess and the muon g-2 without conflicting with the LHC constraints. We also comment on the possible explanations in the gauge mediation supersymmetry breaking scenario.
