Description
We report our experience on using ROOT package TMVA for multivariate data analysis, for a
problem of tau tagging in the framework of heavy charged MSSM Higgs boson searches at the LHC.
With a generator level analysis, we investigate how in the ideal case tau tagging could be performed
and hadronic tau decays separated from the hadronic jets of QCD multi-jet background present in LHC
experiments. A successful separation of the Higgs signal from the background requires a rejection
factor of 10^5 or better against the QCD background. The tau tagging efficiency and background
rejection are studied with various MVA classifiers.
