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

Abstract

AbstractWe 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, . 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.
