Measurement of diboson production and precision EFT constraints in ATLAS

These proceedings summarize the latest progress by the ATLAS Experiment at the LHC in measuring diboson production and related searches for physics beyond Standard Model via anomalous gauge couplings with the latest Effective Field Theory approach. The most recent measurements of $W^{+}{W}^{-}\to {\mathrm{\ell }}^{+}\nu {\mathrm{\ell }}^{-}\bar{\nu }$, $W^{\pm }Z\to 3\mathrm{\ell }1\nu$ and $Z(\to {\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-})\gamma$ measurements with ATLAS full Run 2 dataset are presented, along with the highlights of the first evidence of $W^{+}{W}^{-}$ charge asymmetry, the first measurement of CP-violation sensitive observables in $WZ$, and, for the first time at the LHC, $SU(2{)}_L\otimes U(1{)}_Y$ fully gauge invariant anomalous neutral triple gauge coupling limits with $Z(\to {\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-})\gamma$ process.
