Search for the limits on anomalous neutral triple gauge couplings via $ZZ$ production in the $\ell \ell \nu \nu$ channel at FCC-hh

Abstract

This paper presents the projections on the anomalous neutral triple gauge couplings ($aNTGC$) via $pp\to ZZ$ production in the 2$\ell$2$\nu$ final state at a 100 TeV proton-proton collider, \verb"FCC-hh". %100 TeV center of mass energy of The realistic \verb"FCC-hh" detector environments and its effects taken into account in the analysis. The study is carried out in the mode where one Z boson decays into a pair of same-flavor, opposite-sign leptons (electrons or muons) and the other one decays to the two neutrinos. The new bounds on the charge-parity (CP)-conserving couplings $C_{\tilde{B}W}/{\Lambda }^4$ and CP-violating couplings $C_{WW}/{\Lambda }^4$, $C_{BW}/{\Lambda }^4$ and $C_{BB}/{\Lambda }^4$ achived at 95\% Confidence Level (C.L.) using the transverse momentum of the dilepton system ($p_T^{\ell \ell }$) are $[-0.042,+0.042]$, $[-0.050,+0.050]$, $[-0.050,+0.050]$, and $[-0.048,+0.048]$ in units of TeV${}^{-4}$, respectively.
