Özet
We investigate the sensitivity of the anomalous dimension-8 neutral triple gauge couplings via process pp -> 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-(B) over tildeW/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-(B) over tildeW/Lambda(4), C-BB/Lambda(4), C-WW/Lambda(4) and C-BW/Lambda(4) couplings for HL-LHC (HE-LHC) as [-0.38;0.38]([-0.12;0.12]), [-0.21;0.21]([-0.085;0.085]), [-1.08;1.08]([-0.38;0.38]) and [-0.48;0.48]([-0.25;0.25]), respectively. They are better than the experimental limits obtained by LHC. (C) 2020 The Author(s). Published by Elsevier B.V.
