| dc.description.abstract | A search for a beyond the Standard Model charged Higgs boson through a combined $W\gamma$ resonance is presented. The final state consists of an electron or a muon accompanied by at least one photon. The search is uses 140 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 13 TeV collected using the ATLAS detector within the Large Hadron Collider. A binned maximum likelihood fit is performed with signal samples in the mass range of 110 to 200 GeV. The invariant mass of the $W\gamma$ system is used as a discriminant in the statistical analysis methods. In this analysis, we place exclusion limits on producing a fermiophobic charged Higgs decaying to a $W\gamma$ pair through focuses on model-dependent and model-independent approaches. Exclusion limits are also presented for producing a fermiophobic charged Higgs through a di-Higgs Drell-Yan process with the requirement of at least one charged Higgs producing a $W\gamma$ pair of particles in the final state. As such, we extend the exclusion limits to cover the mass range of Beyond the Standard Model Higgs of 110-200 GeV. | |
