Title: | Evidence for the production of three massive vector bosons with the ATLAS detector | Authors: | Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2019 | Publisher: | Elsevier | Serial title, monograph or event: | Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics | Volume: | 798 | Abstract: | A search for the production of three massive vector bosons in proton–proton collisions is performed using data at √s=13TeV recorded with the ATLAS detector at the Large Hadron Collider in the years 2015–2017, corresponding to an integrated luminosity of 79.8fb−1. Events with two same-sign leptons (electrons or muons) and at least two reconstructed jets are selected to search for WWW→ ν νqq. Events with three leptons without any same-flavour opposite-sign lepton pairs are used to search for WWW→ ν ν ν, while events with three leptons and at least one same-flavour opposite-sign lepton pair and one or more reconstructed jets are used to search for WWZ→ νqq . Finally, events with four leptons are analysed to search for WWZ→ ν ν and WZZ→qq . Evidence for the joint production of three massive vector bosons is observed with a significance of 4.1 standard deviations, where the expectation is 3.1 standard deviations. | URI: | https://hdl.handle.net/10316/107231 | DOI: | 10.1016/j.physletb.2019.134913 | Rights: | openAccess |
