Limits on neutral Higgs boson production in the forward region in pp collisions at √s=7 TeV Camboni, Alessandro Comerma Montells, Albert Garrido Beltrán, Lluís Graciani Díaz, Ricardo Graugés Pous, Eugeni López Asamar, Elias Picatoste Olloqui, Eduardo Potterat, Cédric Rives Molina, Vicente José Ruiz, Hugo (Ruiz Pérez) Vázquez Gómez, Ricard Abellan Beteta, Carlos Calvo Gómez, Míriam Oyanguren Campos, Arantza de Ruiz Valls, Pablo Vilasis-Cardona, Xavier LHCb Collaboration Hadrons Gran Col·lisionador d'Hadrons Teoria quàntica Gravitació Teoria quàntica de camps Hadrons Large Hadron Collider (France and Switzerland) Quantum theory Gravitation Quantum field theory Limits on the cross-section times branching fraction for neutral Higgs bosons, produced in pp collisions at s√=7s=7 TeV, and decaying to two tau leptons with pseudorapidities between 2.0 and 4.5, are presented. The result is based on a dataset, corresponding to an integrated luminosity of 1.0 fb−1, collected with the LHCb detector. Candidates are identified by reconstructing final states with two muons, a muon and an electron, a muon and a hadron, or an electron and a hadron. A model independent upper limit at the 95% confidence level is set on a neutral Higgs boson cross-section times branching fraction. It varies from 8.6 pb for a Higgs boson mass of 90 GeV to 0.7 pb for a Higgs boson mass of 250 GeV, and is compared to the Standard Model expectation. An upper limit on tan β in the Minimal Supersymmetric Model is set in the mmaxh0mh0max scenario. It ranges from 34 for a CP -odd Higgs boson mass of 90 GeV to 70 for a pseudo-scalar Higgs boson mass of 140 GeV. 2016-06-07T08:00:29Z 2016-06-07T08:00:29Z 2013-05-27 2016-06-07T08:00:35Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1126-6708 https://hdl.handle.net/2445/99294 628978 eng Reproducció del document publicat a: http://dx.doi.org/10.1007/JHEP05(2013)132 Journal of High Energy Physics, 2013, vol. 5, num. 132 http://dx.doi.org/10.1007/JHEP05(2013)132 info:eu-repo/grantAgreement/EC/FP7/261323/EU//EGI-INSPIRE cc-by (c) LHCb Collaboration et al., 2013 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess application/pdf Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
