TL;DR
This paper explores the possibility that a 96 GeV Higgs boson explains observed excesses in di-photon and b-jet spectra, using a 2HDM type-III model consistent with experimental data.
Contribution
It demonstrates that the 2HDM type-III can simultaneously fit the CMS and LEP excesses at 96 GeV within 1σ, satisfying all constraints.
Findings
2HDM type-III can explain both excesses simultaneously
Model fits data at 1σ level
Satisfies all experimental and theoretical constraints
Abstract
Recently the CMS collaboration reported a local excess in the di-photon spectrum at 96 GeV. The same mass range concurs with a local excess in the invariant mass spectrum in four-jet events collected at LEP. In this contribution we show that at 1 level the 2HDM type-III can perfectly fit both excesses simultaneously, while satisfying all experimental and theoretical constraints.
