Measurement of the $H \to \tau\tau$ cross section in CMS and possible constraints on tanbeta

The achievable precision of the cross section times branching ratio measurement from the event rates is estimated for the MSSM H /Arightward arrowtautau decay in the associated production process ggrightward arrowbbmacronH/A at large tanbeta in CMS. This work demonstrates that the above production and decay process exhibit a large sensitivity to tanbeta and thus adds as a significant observable to a global fit of the SUSY parameters. To illustrate this potential an example is given concerning the achievable tanbeta determination accuracy that can be reached from the event rates and for a given set of SUSY parameters and their measurement uncertainties.
