Abstract
In this paper we give high-precision theoretical predictions for cross sections of the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}ZH$ for future electron-positron colliders. The calculations are performed using the sanc system. They include complete one-loop electroweak radiative corrections, as well as the longitudinal polarization of initial beams. Numerical results are given for the center-of-mass energy range $\sqrt{s}=250--1000\text{ }\text{ }\mathrm{GeV}$ with various polarization degrees.
Highlights
The clean signatures of the reactions at eþe− colliders combined with the polarization effect of initial particles can increase the precision of theoretical predictions for various observables of Standard Model processes [1].Future linear collider projects such as ILC [2] and CLIC [3] are designed to produce polarized beams—up to 80%for electrons and 60% for positrons
In this paper we present the results for the complete oneloop electroweak (EW) radiative corrections (RCs) to Higgsstrahlung for arbitrary longitudinal polarization of
In the paper we have investigated the complete one-loop electroweak radiative corrections for the process eþe− → ZH with longitudinal polarization of positron and electron beams in a wide center-of-mass energy range
Summary
The clean signatures of the reactions at eþe− colliders combined with the polarization effect of initial particles can increase the precision of theoretical predictions for various observables of Standard Model processes [1]. In this paper we present the results for the complete oneloop electroweak (EW) radiative corrections (RCs) to Higgsstrahlung for arbitrary longitudinal polarization of. For the numerical evaluation of the process we use the MCSANC integrator [21,22] which has been extended for the longitudinally polarized eþ and e− beams (MCSANCEE integrator). It was previously used for the Bhabha process [23].
