论文摘要
本文报告了使用Proton-Proton碰撞数据在$ \ sqrt {s} = 13 $ tev的中心能量中，使用Proton-Proton碰撞数据搜索了重谐解为$ ww $，$ zz $或$ wz $。从2015年至2018年，在大型强子对撞机上，与ATLAS检测器一起记录了对应于139 $ \ mathrm {fb^{ - 1}} $ 139 $ \ mathrm {fb^{ - 1}} $的数据的数据。对最终状态进行了搜索，其中一个$ W $或$ Z $玻色子会衰变，另一个$ W $ Boson或$ Z $ boson腐烂。发现数据通过预期的背景很好地描述。重型标量，向量或张量共振的生产横截面的上限在质量范围300-5000 GEV中得出，在具有扭曲的额外尺寸或包括重型矢量三重态的标准模型扩展的背景下。根据假定的模型，考虑了通过Gluon-Gluon融合，Drell-Yan或Vector-Boson融合的生产。
This paper reports on a search for heavy resonances decaying into $WW$, $ZZ$ or $WZ$ using proton-proton collision data at a centre-of-mass energy of $\sqrt{s}=13$ TeV. The data, corresponding to an integrated luminosity of 139 $\mathrm{fb^{-1}}$, were recorded with the ATLAS detector from 2015 to 2018 at the Large Hadron Collider. The search is performed for final states in which one $W$ or $Z$ boson decays leptonically, and the other $W$ boson or $Z$ boson decays hadronically. The data are found to be described well by expected backgrounds. Upper bounds on the production cross sections of heavy scalar, vector or tensor resonances are derived in the mass range 300-5000 GeV within the context of Standard Model extensions with warped extra dimensions or including a heavy vector triplet. Production through gluon-gluon fusion, Drell-Yan or vector-boson fusion are considered, depending on the assumed model.
