Search for Higgs pair-production in the bb$\tau$$\tau$ final state with the ATLAS detector

We present the result of Higgs boson pair production and subsequent decay into the bbττ channel in pp collision at centre-of-mass energy of 8 TeV using the ATLAS detector at the LHC. This analysis is based on the full 2012 data corresponding to a total luminosity of 20.3 fb−1 . We have explored resonant and non-resonant production of Higgs pair in the final state where one τ decays leptonically and the other hadronically. The observed upper limit at 95% CL on the cross-section σ (gg → hh) is found to be 1.6 pb for non-resonant production. For resonant production the observed limit ranges between 4.2 pb for mH = 260 GeV and 0.46 pb for mH = 1000 GeV. H is the heavy scalar, which decays to two Standard-Model-like Higgs, h.
