摘要

我们给出了gg→gH通道中希格斯玻色子产生的完全次一级电弱修正的计算。采用微分方程法结合优化主积分的选择来完成主积分的计算。我们考虑了三种不同的重整化方案。在第一阶，微分分布和总截面对重整化方案有很强的依赖性。然而，一旦考虑到电弱校正，这些差异就会被大大抑制。对于Gμ方案，电弱校正约占总截面的4.3%。重要的是，我们发现电子束修正对希格斯横向动量有很强的依赖性。

Electroweak corrections to Higgs+jet production in gluon fusion

We present the calculation of complete next-to-leading order electroweak corrections to the Higgs boson production in gg → gH channel. We apply the method of differential equations combined with the selection of optimized master integrals to accomplish the calculation of master integrals. We consider three distinct renormalization schemes. At leading order, the differential distributions and the total cross section show a strong dependence on the renormalization scheme. However, these discrepancies are considerably suppressed once electroweak corrections are taken into account. For G_μ scheme, the electroweak correction amounts to approximately 4.3% of the total cross section. Importantly, we find that the EW corrections exhibit a strong dependence on Higgs transverse momentum.
