DESCRIPTION:Speakers: Anastasia Kurova (NRNU MEPhI)\nRun2 sensitivity to q
 uartic anomalous gauge couplings was estimated for ATLAS experiment at LHC
  with increased energy of proton-proton collisions $\\sqrt{s} = 13$ TeV an
 d expected 40 fb$^{-1}$ (2016) and 100 fb$^{-1}$ (2016-2017) of integral l
 uminosity. Simulation of $Z\\gamma\\gamma$ process with anomalous $ZZ\\gam
 ma\\gamma$ and $Z\\gamma\\gamma\\gamma$ couplings was performed using VBFN
 LO MC generator. Differential distributions on four body invariant mass of
  final state particles was used for extraction of expected limits on Effec
 tive Field Theory parameters $f_{T0}/\\Lambda^{4}\, f_{T5}/\\Lambda^{4}\,
  f_{T9}/\\Lambda^{4}\, f_{M2}/\\Lambda^{4}\, f_{M3}/\\Lambda^{4}$. Comb
 ined limits are obtained from two charged leptonic decay channels of Z bos
 on ($Z\\gamma\\gamma\\rightarrow l^{+}l^{−}\\gamma\\gamma$\, where $l = 
 e$ or $\\mu$). Unitarity of expected limits was studied using dipole form 
 factor.\n\nhttps://indico.particle.mephi.ru/event/4/contributions/658/
