  A search for neutral Higgs bosons in the minimal supersymmetric extension of
the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is
performed, using events recorded by the CMS experiment at the LHC. The dataset
corresponds to an integrated luminosity of 24.6 inverse femtobarns, with 4.9
inverse femtobarns at 7 TeV and 19.7 inverse femtobarns at 8 TeV. To enhance
the sensitivity to neutral MSSM Higgs bosons, the search includes the case
where the Higgs boson is produced in association with a b-quark jet. No excess
is observed in the tau-lepton-pair invariant mass spectrum. Exclusion limits
are presented in the MSSM parameter space for different benchmark scenarios,
m[h,max}, m[h,mod+], m[h,mod-], light-stop, light-stau, tau-phobic, and
low-m[H]. Upper limits on the cross section times branching fraction for gluon
fusion and b-quark associated Higgs boson production are also given.
