The Hybrid Chain Corrections for ZZ and γγ Pair Production in the SM at Future e +e − Colliders

EasyChair Preprint 10661

Abstract

We present the precision predictions for neutral gauge boson pair production in the standard model (SM) at

the future e⁺e⁻ colliders including the electron hybrid chain electroweak correction. The differential cross section of e⁺e⁻ → ZZ, γγ by the renormalized electron hybrid chain propagator (RHCP) is calculated analytically. Besides, the differential cross section between cases of the RHCP and Born level are compared. The numerical results show that, the relative correction of RHCP with respect to tree level for e⁺e⁻→ ZZ are located in a

rannge mainly from 2.52% to 3.41% in the range of the center-of-mass energy from 184GeV to 300GeV, and the radiative corrections increases with the increase of incident electron energy for e⁺e⁻ → γγ in the incident energy from 1GeV to 200GeV.

Keyphrases: Hybrid chain propagator, Relative correction., cross section, standard model
