Abstract: Results of a search for the production of Higgs boson pairs are presented. In this search one Higgs boson decays to a pair of b-quarks, and the other Higgs boson decays to a tau lepton pair where the tau leptons decay hadronically. The search is based on proton-proton collision data recorded by the CMS experiment at √s= 8 TeV in 2012, corresponding to an integrated luminosity of 18.3 fb−1. The resonant and the non-resonant productions of Higgs boson pairs are studied. No significant excess with respect to the background-only hypothesis is observed in the data and therefore corresponding upper limits on cross section times branching ratio are set. In the case of resonant HH boson production, the limit on σ(pp→X)×BR(X→HH) for a resonance of spin 0 (spin 2) and mass mX, ranges from 5.42 pb (3.97 pb) at mX= 300 GeV to 0.14 pb (0.14 pb) at mX= 1000 GeV. The limit on non-resonant production amounts to approximately 50 times the rate predicted by the SM. | ||
