Search for neutral Higgs bosons decaying to tau pairs in pp collisions
at sqrt(s)=7 TeV    [PDF]

CMS Collaboration

A search for neutral Higgs bosons decaying to tau pairs at a center-of-mass
energy of 7 TeV is performed using a dataset corresponding to an integrated
luminosity of 4.6 inverse femtobarns recorded by the CMS experiment at the LHC.
The search is sensitive to both the standard model Higgs boson and to the
neutral Higgs bosons predicted by the minimal supersymmetric extension of the
standard model (MSSM). No excess of events is observed in the tau-pair
invariant-mass spectrum. For a standard model Higgs boson in the mass range of
110-145 GeV upper limits at 95% confidence level (CL) on the production cross
section are determined. We exclude a Higgs boson with m(H)=115 GeV with a
production cross section 3.2 times of that predicted by the standard model. In
the MSSM, upper limits on the neutral Higgs boson production cross section
times branching fraction to tau pairs, as a function of the pseudoscalar Higgs
boson mass, m(A), sets stringent new bounds in the parameter space, excluding
at 95% CL values of tan(beta) as low as 7.1 at m(A) = 160 GeV.
