Probing neutral triple gauge couplings via Z_(γ)(l+l-y)production at e^(+)e^(-)colliders
摘要
Neutral triple gauge couplings(nTGCs)are absent in the Standard Model(SM)and at the dimension-6 level in the Standard Model Effective Field Theory(SMEFT),arising first from dimension-8 operators.As such,they provide a unique window for probing new physics beyond the SM.These dimension-8 operators can be mapped to nTGC form factors whose structure is consistent with the spontaneously-broken electroweak gauge symmetry of the SM.In this work,we study the probes of nTGCs in the reaction e^(+)e^(-)→Z_(γ)with Z→l^(+)l^(-)(l=e,μ)at an e^(+)e^(-)collider.We perform a detector-level simulation and analysis of this reaction at the Circular Electron Positron Collider(CEPC)with collision energy√s=240 GeV and an integrated luminosity of 20 ab−1.We present the sensitivity limits on probing the new physics scales of dimension-8 nTGC operators via measurements of the corresponding nTGC form factors.
