ABJM理论中的双环八点振幅

The two-loop eight-point amplitude in ABJM theory

Song He, Yu-tin Huang, Chia-Kai Kuo, Zhenjie Li

摘要:

本文给出了三维$\mathcal{N}=6$ Chern-Simons物质理论中散射振幅的双环修正。我们使用八点的情况作为我们的主要例子,但该方法推广到所有的多重性。被积函数是完全固定的对偶共形对称性,最大切割,软共线行为的约束和从消失的奇多重振幅。在进行了Higgs正则化积分后,积分结果表明红外发散再次与${\cal N}=4$超级Yang-Mills相同。减去发散项后的有限部分是对偶共形不变的,并尊重各种对称性,具有一致的超越性权重2,具有良好的解析结构。

英文摘要:

In this paper, we present the two-loop correction to scattering amplitudes in three-dimensional $\mathcal{N}=6$ Chern-Simons matter theory. We use eight-point case as our main example, but the method generalizes to all multiplicities. The integrand is completely fixed by dual conformal symmetry, maximal cuts, constraints from soft-collinear behavior and from vanishing of odd-multiplicity amplitudes. After performing integrations with Higgs regularizations, the integrated results demonstrate that the infrared divergence is again identical to that of ${\cal N}=4$ super Yang-Mills. After subtracting divergences, the finite part is dual conformal invariant, and respects various symmetries; it has uniform transcendentality weight two and exhibits nice analytic structure.
