论文摘要
通过衡量其自我互动来了解希格斯的潜力是回答几个大问题的基础,例如electroweak对称性破坏,电子eak baryogenese,electroweak epter eper transition和electroweak真空稳定性。探测希格斯潜力的最有希望的方法是在高能量乘员处检测Higgs Boson对最终状态。在本次演讲中,我们通过考虑到无限顶部夸克质量限制的近似值,报告了Di-higgs Gluon融合过程的最新扰动计算。有限的顶级夸克质量效应还与几个近似方案结合在一起,这在现象学应用中至关重要。我们在$ \ Mathcal {o}(α_s^5)$上显示出非常好的渐近扰动收敛,并证明其余的规模不确定性仅在百分比级别。
Understanding the Higgs potential by measuring its self-interactions is fundamental in answering several big questions, such as electroweak symmetry breaking, electroweak baryogenesis, electroweak phase transition, and electroweak vacuum stability. The most promising way to probe the Higgs potential is to detect Higgs boson pair final state at high-energy colliders. In this talk, we report a recent perturbative calculation for the di-Higgs gluon-fusion process by taking into account N$^3$LO QCD radiative corrections in the approximation of infinite top quark mass limit. Finite top quark mass effects are also incorporated with several approximate schemes, which are known to be crucial in phenomenological applications. We show a very good asymptotic perturbative convergence at $\mathcal{O}(α_s^5)$, and demonstrate that the remaining scale uncertainty is only at percent level.
