We report results from a search for neutral Higgs bosons produced in association with b quarks using data recorded by the D0 experiment at the Fermilab Tevatron Collider and corresponding to an integrated luminosity of 7.3 fb−1. This production mode can be enhanced in several extensions of the standard model (SM) such as in its minimal supersymmetric extension (MSSM) at high tan [beta]. We search for Higgs bosons decaying to tau pairs with one tau decaying to a muon and neutrinos and the other to hadrons. The data are found to be consistent with SM expectations, and we set upper limits on the cross section times branching ratio in the Higgs boson mass range from 90 to 320 GeV/c2. We interpret our result in the MSSM parameter space, excluding tan [beta] values down to 25 for Higgs boson masses below 170 GeV/c2.

We report results from a search for neutral Higgs bosons decaying to tau pairs produced in association with a b-quark in 1.6 fb−1 of data taken from June 2006 to March 2008 with the D0 detector at Fermi National Accelerator Laboratory. The final state includes a muon, hadronically decaying tau, and jet identified as coming from a b-quark. We set cross section times branching ratio limits on production of such neutral Higgs bosons [phi] in the mass range from 90 GeV to 160 GeV. Exclusion limits are set at the 95% Confidence Level for several supersymmetric scenarios.

We report results from a search for neutral Higgs bosons decaying to tau pairs produced in association with a b-quark in 1.2 fb−1 of data taken from June 2006 to August 2007 with the D0 detector at Fermi National Accelerator Laboratory. The final state includes a muon, hadronically decaying tau and jet identified as coming from a b-quark. We set cross section times branching ratio limits on production of such neutral Higgs bosons [phi] in the mass range from 90 GeV/c2 to 160 GeV/c2.

Download Search for Neutral Higgs Bosons Decaying to Tau Pairs in P Anti-p Collisions at S**(1/2) Book in PDF, ePub and Kindle
A search for the production of neutral Higgs bosons ? decaying into ?+?− final states in p{bar p} collisions at a center-of-mass energy of 1.96 TeV is presented. The data, corresponding to an integrated luminosity of approximately 325 pb−1, were collected by the D0 experiment at the Fermilab Tevatron Collider. Since no excess compared to the expectation from standard model processes is found, limits on the production cross section times branching ratio are set. The results are combined with those obtained from the D0 search for ?b({bar b}) → b{bar b}b({bar b}) and are interpreted in the minimal supersymmetric standard model.

Download Search for Neutral MSSM Higgs Bosons Decaying to a Pair of Tau Leptons in Pp Collisions Book in PDF, ePub and Kindle
Our 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 fb-1, with 4.9 fb-1 at 7 TeV and 19.7 fb-1 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 hmod -, light-stop, light-stau, [tau]-phobic, and low-m H. Lastly, upper limits on the cross section times branching fraction for gluon fusion and b-quark associated Higgs boson production are also given.

Download Search for Higgs Bosons Decaying Into Tau Pairs in Ppbar Collisions at Book in PDF, ePub and Kindle
A search for neutral Higgs bosons decaying into tau pairs is presented using data in p$\bar{p}$ collisions at √s = 1.96 TeV. One of the tau leptons is identified via its decay into an electron or muon and the other via its decay into a hadronic final state. The data, corresponding to an integrated luminosity of around 1.0 fb-1, were collected with the D0 detector at the Fermilab Tevatron collider between April 2002 and February 2006. No significant excess of events above the background expectation is observed and limits on the cross section times branching ratio for neutral Higgs bosons decaying into tau pairs, p$\bar{p}$ → [Phi] → [tau]+[tau]-, are set. The cross section limits are interpreted as exclusions in the parameter space of the minimal supersymmetric Standard Model, resulting in exclusions in the range 40
