The projections on And Couplings via production in HL-LHC and HE-LHC

We investigate the sensitivity of the anomalous dimension-8 neutral triple gauge couplings via process $pp\to \nu \nu \gamma $ with fast detector simulation including pile-up effects for the post LHC experiments. The transverse momentum of the final state photon and missing energy transverse distributions are considered in the analysis. We obtain the sensitivity to the ${C}_{\stackrel{˜}{B}W}/{\Lambda }^{4}$, ${C}_{BB}/{\Lambda }^{4}$, ${C}_{WW}/{\Lambda }^{4}$ and ${C}_{BW}/{\Lambda }^{4}$ couplings at HL-LHC and HE-LHC with an integrated luminosity of 3 ab$^{−1}$ and 15 ab$^{−1}$, respectively. Finally, our numerical results show that one can reach the constraints at 95% confidence level without systematic error on ${C}_{\stackrel{˜}{B}W}/{\Lambda }^{4}$, ${C}_{BB}/{\Lambda }^{4}$, ${C}_{WW}/{\Lambda }^{4}$ and ${C}_{BW}/{\Lambda }^{4}$ couplings for HL-LHC (HE-LHC) as $\left[-0.38;0.38\right]\left(\left[-0.12;0.12\right]\right)$, $\left[-0.21;0.21\right]\left(\left[-0.085;0.085\right]\right)$, $\left[-1.08;1.08\right]\left(\left[-0.38;0.38\right]\right)$ and $\left[-0.48;0.48\right]\left(\left[-0.25;0.25\right]\right)$, respectively. They are better than the experimental limits obtained by LHC.
