High-precision limits on $W$-$W'$ and $Z$-$Z'$ mixing from diboson production using the full LHC Run 2 ATLAS data set / Pankov, A.A. (Gomel State Tech. U., ICTP ; Minsk, Inst. Nucl. Problems ; Dubna, JINR) ; Osland, P. (Bergen U.) ; Serenkova, I.A. (Gomel State Tech. U., ICTP) ; Bednyakov, V.A. (Dubna, JINR)
The full ATLAS Run 2 data set with time-integrated luminosity of 139 fb$^{-1}$ in the diboson channels in hadronic final states is used to probe a simple model with an extended gauge sector (EGM), proposed by Altarelli et al., and often taken as a convenient benchmark by experimentalists. [...]
