利用衰变成玻色子对H->；伽马，H->；ZZ*->；4L和H->；WW*->；L NU L NU，测量了最近发现的希格斯玻色子的产生性质和耦合。这些结果是基于欧洲核子研究中心大型强子对撞机上的ATLAS实验记录的完整的pp碰撞数据样本，在根S=7TeV和根S=8TeV的质心能量下，对应的积分光度约为25fB(-1)。报道了通过矢量-玻色子融合产生希格斯玻色子的证据。给出了联合拟合探测Higgs玻色子耦合到费米子和玻色子的结果，以及对环诱导产生和衰变模式的反常贡献。所有测量结果都与标准模型希格斯玻色子的预期一致。(C)2013年欧洲核子研究组织。爱思唯尔出版，版权所有。
Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H -> gamma gamma, H -> ZZ* -> 4l and H -> WW* -> l nu l nu. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of root s = 7 TeV and root s = 8 TeV, corresponding to an integrated luminosity of about 25 fb(-1). Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson. (C) 2013 CERN. Published by Elsevier B.V. All rights reserved.
