Study of s-channel Charged Higgs Production in CMS

CMS potential for study of the s-channel $H^{\pm}$-boson production via light quark annihilation is investigated for large values of $\tan\beta$ ($=20\div 50$) and relatively light charge Higgs boson ($M_H = 200 \div 400$ GeV). An appropriate parameterisation for $M_{\top}(j, \ETM)$-distributions of the signal and background events is proposed, which provides the determination of the charged Higgs mass and $\tan\beta$ parameter.
