Search for higgs boson pair production in the bbττ final state in proton-proton collisions at (s)=8 TeV

Results are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a τ lepton pair. This work is based on proton-proton collision data collected by the CMS experiment at √ s = 8 TeV, corresponding to an integrated luminosity...

Adli Q Science (General) QC Physics Results are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a τ lepton pair. This work is based on proton-proton collision data collected by the CMS experiment at √ s = 8 TeV, corresponding to an integrated luminosity of 18.3 fb−1 . Resonant and nonresonant modes of HH production have been probed and no significant excess relative to the background-only hypotheses has been found in either mode.

Limits from the combination have been set on resonant HH production by an unknown particle X in the mass range mX = 300 GeV to mX = 1000 GeV. For resonant production of spin 0 (spin 2) particles, the observed 95% CL upper limit is 1.13 pb (1.09 pb) at mX = 300 GeV and to 21 fb (18 fb) at mX = 1000 GeV. For nonresonant HH production, a limit of 43 times the rate predicted by the standard model has been set.
