在本文中，我们提出了 ILC 标准模型 (SM) 中三光子产生的精确预测，包括完整的次领先 (NLO) 电弱 (EW) 校正、高阶初始态辐射 (ho ISR) 贡献和束致辐射效应。我们提出了当 s≥ 200 GeV 时各种碰撞能量的 LO 和 NLO EW+ ho ISR+ 束致辐射校正的总截面以及 ILC s= 500 GeV 时最终光子的运动学分布，并发现 NLO EW 校正、ho ISR 贡献和束致辐射效应对于探索 e+ e−→ γ γ γ 过程非常重要。
In this paper, we present the precision predictions for three photon production in the standard model (SM) at the ILC including the full next-to-leading (NLO) electroweak (EW) corrections, high order initial state radiation (ho ISR) contributions and beamstrahlung effects. We present the LO and the NLO EW+ ho ISR+ beamstrahlung corrected total cross sections for various colliding energy when s≥ 200 GeV and the kinematic distributions of final photons with s= 500 GeV at ILC, and find that the NLO EW corrections, the ho ISR contributions and the beamstrahlung effects are important in exploring the process e+ e−→ γ γ γ.
