| 英文摘要 | A search for heavy resonances decaying into a higgs boson (h) and a new particle (x) is reported, utilizing 36.1 fb(-1) of proton-proton collision data at root s = 13 tev collected during 2015 and 2016 with the atlas detector at the cern large hadron collider. the particle xis assumed to decay to a pair of light quarks, and the fully hadronic final state xh -> q (q) over bar 'b (b) over bar is analysed. the search considers the regime of high xh resonance masses, where the x and h bosons are both highly lorentz-boosted and are each reconstructed using a single jet with large radius parameter. a two-dimensional phase space of xh mass versus x mass is scanned for evidence of a signal, over a range of xh resonance mass values between 1 tev and 4 tev, and for x particles with masses from 50 gev to 1000 gev. all search results are consistent with the expectations for the background due to standard model processes, and 95% cl upper limits are set, as a function of xh and x masses, on the production cross-section of the xh -> q (q) over bar 'b (b) over bar resonance.
