Sensitivity on anomalous neutral triple gauge couplings via ZZ production at FCC-hh

Abstract

Abstract We study the sensitivity of anomalous neutral triple gauge couplings (aNTGC) via $$pp \rightarrow ZZ$$ pp→ZZ production in the 4$$\ell $$ ℓ channel at 100 TeV center of mass energy of future circular hadron collider, FCC-hh. The analysis including the realistic detector effects is performed in the mode where both Z bosons decay into same-flavor, oppositely charged lepton pairs. The sensitivities to the charge–parity (CP)-conserving couplings $$C_{{\tilde{B}}W} / \Lambda ^{4}$$ CB~W/Λ4 and CP-violating couplings $$C_{WW} / \Lambda ^{4}$$ CWW/Λ4 , $$C_{BW} / \Lambda ^{4}$$ CBW/Λ4 and $$C_{BB} / \Lambda ^{4}$$ CBB/Λ4 obtained at 95% Confidence Level using the invariant mass distribution of the 4$$\ell $$ ℓ system reconstructing the leading and sub-leading Z boson candidates are $$[-\,0.09, \,\, +\,0.09]$$ [-0.09,+0.09] , $$[-\,0.21, \,\, +\,0.21]$$ [-0.21,+0.21] , $$[-\,0.26, \,\, +\,0.26]$$ [-0.26,+0.26] , and $$[-\,0.10, \,\, +\,0.10]$$ [-0.10,+0.10] in units of $$\hbox {TeV}^{-4}$$ TeV-4 , respectively.
