英文摘要	A search for higgs boson pair production pp -> hh is performed with 19.5 fb(-1) of proton-proton collision data at root s = 8tev, which were recorded by the atlas detector at the large hadron collider in 2012. the decay products of each higgs boson are reconstructed as a high-momentum b (b) over bar system with either a pair of small-radius jets or a single large-radius jet, the latter exploiting jet substructure techniques and associated b-tagged track-jets. no evidence for resonant or non-resonant higgs boson pair production is observed. the data are interpreted in the context of the randall-sundrum model with a warped extra dimension as well as the two-higgs-doublet model. an upper limit on the cross-section for pp -> g(kk)* -> hh -> b (b) over barb (b) over bar of 3.2 (2.3) fb is set for a kaluza-klein graviton g(kk)* mass of 1.0 (1.5) tev, at the 95 % confidence level. the search for non-resonant standard model hh production sets an observed 95 % confidence level upper limit on the production cross-section sigma(pp -> hh -> b (b) over barb (b) over bar) of 202 fb, compared to a standard model prediction of s(pp -> hh -> b (b) over barb (b) over bar) = 3.6 +/- 0.5fb.
