On the phenomenology of a two-Higgs-doublet model with maximal CP symmetry at the LHC, II: radiative effects

TL;DR

This paper investigates the effects of a specific two-Higgs-doublet model with maximal CP symmetry on gamma plus heavy-flavour jet production at the LHC and Tevatron, highlighting unique c-jet signatures due to radiative Higgs processes.

Contribution

It introduces the MCPM model's distinctive prediction of c-jet excesses from radiative Higgs production and decay at collider energies.

Findings

Radiative Higgs processes produce heavy-flavour c jets but not b jets.

An excess of c jets over QCD expectations is predicted at Tevatron and LHC.

b jets are consistent with standard QCD processes.

Abstract

The processes proton + antiproton -> gamma + heavy-flavour jet(s) + X and proton + proton -> gamma + heavy-flavour jet(s) + X are studied in the framework of a special two-Higgs-doublet model, the MCPM. As distinguishing feature of this model we find that radiative Higgs-boson production and decay lead to heavy flavour c jets but no b jets in the above processes. Thus, the prediction is that b jets should be given by the normal QCD processes whereas for c jets an excess over the QCD expectation should occur. We present results both for Tevatron and LHC energies.
