| 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 $\sqrt{s} =$ 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 $\mathrm{HH}$ boson production, the limit on $\sigma(\mathrm{pp} \to X) \times \mathrm{BR}(X \to \mathrm{HH})$ for a resonance of spin 0 (spin 2) and mass $m_{X}$, ranges from 5.42 pb (3.97 pb) at $m_{X}=$ 300 GeV to 0.14 pb (0.14 pb) at $m_{X}=$ 1000 GeV. The limit on non-resonant production amounts to approximately 50 times the rate predicted by the SM. | ||
