Enhanced sensitivity achieved by combining multiple decay channels.

Abstract

We present a search for Higgs boson produced in the di-tau modes or via the associated $p\bar{p}\to h+b \to\tau^+\tau^-b$ process at a center-of-mass energy of $\sqrt{s}=$1.96 TeV using up to 1.8-7.3 fb$^{-1}$ of data collected with the D0 and CDF detector at the Fermilab Tevatron collider. In Supersymmetric models Higgs boson production cross section can be significantly enhanced compared to the Standard Model. Additionally the Higgs boson has a significant branching ratio to $\tau$ leptons at all masses. The di-$\tau$ and $b-\tau\tau$ channels complement each other providing best sensitivity for the search in the SUSY parameter space
