Abstract
We study the exclusive decay B_s -> \tau^+ \tau^-$ in the general two Higgs doublet model. We analyse the dependencies of the branching ratio on the model parameters, including the leading order QCD corrections. We found that there is an enhancement in the branching ratio, especially for r_{tb}=\frac{\bar{\xi}_{N,tt}^U}{\bar{\xi}_{N,bb}^D}>1 case. Further, the neutral Higgs effects are detectable for large values of the parameter \bar{\xi}_{N,\tau\tau}^D.
