Title: | Search for a right-handed gauge boson decaying into a high-momentum heavy neutrino and a charged lepton in pp collisions with the ATLAS detector at s=13 TeV | Authors: | Santos, S. P. Amor dos Galhardo, B. 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 a right-handed gauge boson WR, decaying into a boosted right-handed heavy neutrino NR, in the framework of Left-Right Symmetric Models is presented. It is based on data from proton–proton collisions with a centre-of-mass energy of 13TeVcollected by the ATLAS detector at the Large Hadron Collider during the years 2015, 2016 and 2017, corresponding to an integrated luminosity of 80fb−1. The search is performed separately for electrons and muons in the final state. A distinguishing feature of the search is the use of large-radius jets containing electrons. Selections based on the signal topology result in smaller background compared to the expected signal. No significant deviation from the Standard Model prediction is observed and lower limits are set in the WRand NRmass plane. Mass values of the WRsmaller than 3.8–5TeVare excluded for NRin the mass range 0.1–1.8TeV. | URI: | https://hdl.handle.net/10316/107223 | DOI: | 10.1016/j.physletb.2019.134942 | Rights: | openAccess |
