A Supersymmetric Explanation of the Excess of Higgs--Like Events at the LHC and at LEP

TL;DR

This paper proposes that the observed excesses of Higgs-like events at 98 GeV and 125 GeV can be simultaneously explained within the minimal supersymmetric Standard Model by the production and decay of two neutral CP-even Higgs bosons.

Contribution

It introduces a supersymmetric model-based explanation for the Higgs-like signals observed at LEP and LHC, unifying these findings.

Findings

Both excesses can be explained by two different Higgs bosons in the MSSM.

The model predicts specific phenomenological signatures for future experiments.

The explanation is consistent with current experimental uncertainties.

Abstract

The LHC collaborations have recently announced evidence for the production of a "Higgs--like" boson with mass near 125 GeV. The properties of the new particle are consistent (within still quite large uncertainties) with those of the Higgs boson predicted in the Standard Model (SM). This discovery comes nearly ten years after a combined analysis of the four LEP experiments showed a mild excess of Higgs--like events with a mass near 98 GeV. I show that both groups of events can be explained simultaneously in the minimal supersymmetric extension of the SM, in terms of the production and decay of the two neutral CP--even Higgs bosons predicted by this model, and explore the phenomenological consequences of this explanation.
