英文摘要A search is conducted for new resonances decaying into a w or z boson and a 125 gev higgs boson in the nu(nu) over barb (b) over bar, l(+/-)nu b (b) over bar, and l(+)l(-)b (b) over bar final states, where l(+/-) = e(+/-) or mu(+/-), in pp collisions at root s = 13 tev. the data used correspond to a total integrated luminosity of 36.1 fb(-1) collected with the atlas detector at the large hadron collider during the 2015 and 2016 data-taking periods. the search is conducted by examining the reconstructed invariant or transverse mass distributions of wh and zh candidates for evidence of a localised excess in the mass range of 220 gev up to 5 tev. no significant excess is observed and the results are interpreted in terms of constraints on the production cross-section times branching fraction of heavy w' and z' resonances in heavy-vector-triplet models and the cp-odd scalar boson a in two-higgs-doublet models. upper limits are placed at the 95% confidence level and range between 9.0 x 10(-4) pb and 7.3 x 10(-1) pb depending on the model and mass of the resonance.
