Study on Anomalous Neutral Triple-gauge Boson Couplings from Dimension-eight Operators at the HL-LHC

The anomalous neutral triple-gauge boson couplings (aNTGCs) for the $Z\gamma\gamma$ and $Z\gamma Z$ vertices described by dimension-eight operators are examined through the process $pp\to l^{+}l^{-}\gamma$ at High-Luminosity Large Hadron Collider (HL-LHC). We performed an analysis on transverse momentum of photon and angular distribution of charged lepton in the final state including detector effects. Sensitivity limits of the $C_{\tilde{B}W}$, $C_{BB}$ couplings are obtained at $95\%$ C.L. to constrain for the ranges $[-1.88;1.88]$ TeV$^{-4}$, $[-1.47:1.47]$ TeV$^{-4}$ and $[-1.14:1.14]$ TeV$^{-4}$, $[-0.86;0.86]$ TeV$^{-4}$ with an integrated luminosity of $300$ fb$^{-1}$ and $3000$ fb$^{-1}$, respectively.
