Abstract / Description:We present results on the determination of the observable
ratio R=BR(H^+ -> \tau \nu)/BR(H^+ -> t b-bar) of charged
Higgs boson decay rates as a discriminant quantity between
Supersymmetric and non-Supersymmetric models. Simulation of
measurements of this quantity through the analysis of the
charged Higgs production process gb-> t b H^+ and relative
backgrounds in the two above decay channels has been
performed in the context of ATLAS. A ~12-14% accuracy on R
can be achieved for \tan\beta=50, \mHc=300-500 GeV and
after an integrated luminosity of 300 fb^-1. With this
precision measurement, the Large Hadron Collider (LHC)
can easily discriminate between models for the two above
scenarios, so long as \tan\beta > 20.
