In this report the CMS potential for the light charged Higgs boson discovery
in the Minimal Supersymmetric Standard Model is presented. First the latest
results of the Tevatron and LEP experiments on the light charged Higgs search
are reminded. In the rest of the report the perspectives of CMS for the light
charged Higgs search are presented with description of some details of the
analysis. The results are based on the full simulation and reconstruction of
the CMS detector including the systematic uncertainties on the background
determination. Finally the 5σ discovery contour for an integrated
luminosity of 30fb−1 is shown.Comment: 7 pages, 5 figures, presented at IPM conference, May 2005, Tehran,
