Possibility of observing charged Higgs in the single top production via its lepton decay at LHC
Single top quark production through weak interactions is considered to be an
important source of charged Higgs in the Minimal Super Symmetric Standard
Model. In the s-channel single top production having largest cross-section may
appear as a propagator in the form of heavy resonance state decaying to a pair
of top and bottom quark. The process under investigation is , where top quark exclusively decays into a pair
of bottom quark and W boson while W boson subsequently decays to jet and
neutrino. So the final state is characterized by the presence of two b jets,
hadronic decay and missing transverse energy. Within the presence of QCD
multijet and electroweak background events at LHC, it has been demonstrated
that the charged Higgs signal observability is possible within the available
MSSM parameter space (tan, respecting all experimental
and theoretical constraints. In order to show the observability potential of
charged Higgs, the exclusion curves at 95 confidence level and 5
contours are plotted at different integrated luminosities with 14
TeV.Comment: arXiv admin note: substantial text overlap with arXiv:1711.0834
