Search for the Light Charged Higgs in CMS.pdf

IPM Conference and School on Lepton and Hadron Physics, May 15-20 2006, Tehran, Iran 1 Search for the Light Charged Higgs in CMS M. Hashemi IPM, P.O.Box 19395-5531, Tehran, Iran 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. 6 1. Introduction by Tevatron in the D0 and CDF experiments.
