Description
A search is presented for additional neutral Higgs bosons in the τ
τ final state in proton-proton collisions at the LHC. The search is
performed in the context of the minimal supersymmetric extension of the
standard model (MSSM), using the data collected with the CMS detector in
2016 at a center-of-mass energy of 13 TeV, corresponding to an
integrated luminosity of 35.9 fb-1. To enhance the
sensitivity to neutral MSSM Higgs bosons, the search includes production
of the Higgs boson in association with b quarks. No significant
deviation above the expected background is observed. Model-independent
limits at 95% confidence level (CL) are set on the product of the
branching fraction for the decay into τ leptons and the cross
section for the production via gluon fusion or in association with b
quarks. These limits range from 18 pb at 90 GeV to 3.5 fb at 3.2 TeV for
gluon fusion and from 15 pb (at 90 GeV) to 2.5 fb (at 3.2 TeV) for
production in association with b quarks, assuming a narrow width
resonance. In the m h hod + scenario these limits
translate into a 95% CL exclusion of tan β > 6 for neutral Higgs
boson masses below 250 GeV, where tan β is the ratio of the vacuum
expectation values of the neutral components of the two Higgs doublets.
The 95% CL exclusion contour reaches 1.6 TeV for tan β = 60.
