Observability of parameter space for charged Higgs boson in its bosonic decays in two Higgs doublet model Type-1

This study explores the possibility of discovering H±through its bosonic decays,i.e.,H±→W±φ(whereφ=h or A),within the Type-I two Higgs doublet model(2HDM).The main objective is to demonstrate the available parameter space after applying recent experimental and theoretical exclusion limits.We suggest that mH±=150 GeV is the most probable mass for the H±→W±φdecay channel in pp collisions at s1/2=8,13,and 14 TeV.We also report on the application of a modern machine learning approach to a multivariate technique for heavy charged Higgs production in association with a single top quark through weak interaction to demonstrate its observability in comparison with the most relevant Standard Model backgrounds using the neural networks of boosted decision Tree(BDT),likelihood(LH),and multilayer perceptron(MLP).
