A study of the performance of the hadronic recoil in inclusive W and Z boson production is presented. The dataset used corresponds to low pileup LHC runs taken between 2017 and 2018, at both centre-of-mass energies of 5 and 13 TeV. The results show that the resolution is optimal when using the maximal phase space available for the particle clusters in the detector. And an optimization of the...

The measurement of the differential cross section of Z boson production in association with jets (Z+jets) in proton-proton collision at the center-of-mass energy of 13 TeV will be present. The data has been recorded with the CMS detector at the LHC during the year 2015, corresponding to an integrated luminosity of 2.19 fb−1. The goal of analysis is to perform a first measurement at 13 TeV of...

The production of Z bosons in association with a high-energy photon is studied in the neutrino decay channel of the Z boson using pp collisions at √ s = 13 TeV. The analysis uses a data sample with an integrated luminosity of 36.1 fb−1 collected by the ATLAS detector at the LHC in 2015 and 2016. Candidate Zγ events with invisible decays of the Z boson are selected by requiring significant...

The talk will present an observation of electroweak production of a same-sign W boson pair in association with two jets using 36.1 fb−1 of proton-proton collision data recorded by the ATLAS detector at a center-of-mass energy of 13 TeV. Events containing two same-sign leptons, electron or muon, and at least two jets, are selected.

At ICHEP2018 conference, ATLAS presented its first observations of same-sign WW and WZ vector boson scattering processes, the latter of which was considered as the 1st observation of such process at LHC, leading to a collaboration wide highlight at the ICHEP2018 conference. It is a very important milestone to probe the SM-EWK symmetry breaking and Higgs unitarization mechanism in the VBS...

Distinguishing quark-initiated from gluon-initiated jets is useful for many measurements and searches at the LHC. Development of tools for distinguishing quark- from gluon-initiated jets are potentially useful. However, there arises difficulty from the topology dependence of quark-versus-gluon jet tagging.The dijet topologies either dijet back to back or djet plus a gamma (quark dominated) or...
