Higgs Boson Searches via Dileptonic Bottomonium Decays

TL;DR

This paper investigates how bottomonium decays into lepton pairs can be used to detect signs of extended Higgs sectors beyond the Standard Model, especially within the Minimal Supersymmetric Standard Model.

Contribution

It demonstrates that bottomonium dileptonic decays could serve as sensitive probes for light Higgs bosons in models beyond the Standard Model.

Findings

Dileptonic decay branching ratios can be significantly enhanced with a light Higgs sector.

Bottomonium decays into leptons are promising channels to explore new Higgs physics.

The effects are particularly notable in the Minimal Supersymmetric Standard Model.

Abstract

We explore the pseudoscalar $\eta_b$ and the scalar $\chi_{b0}$ decays into $\ell^+\ell^-$ to probe whether it is possible to probe the Higgs sectors beyond that of the Standard Model. We, in particular, focus on the Minimal Supersymmetric Standard Model, and determine the effects of its Higgs bosons on the aforementioned bottomonium decays into lepton pairs. We find that the dileptonic branchings of the bottomonia can be sizeable for a relatively light Higgs sector.
