基本物质的色-动能对偶纯引力

Pure Gravities via Color-Kinematics Duality for Fundamental Matter

Henrik Johansson, Alexander Ochirov

摘要:

本文利用色运动学对偶性,给出了计算纯爱因斯坦引力和四维纯超引力中圈级散射振幅的方法。放大器是使用纯(超)杨米尔斯部分的双拷贝和基本物质的双拷贝的额外贡献构建的,这些基本物质被视为鬼。相反统计的状态抵消了玻色子理论中不需要的介子和轴子,以及超引力中的额外物质超多重态。作为一个副产品,我们得到了一个处方,获得振幅在超重力与任意非自相互作用的问题。作为一个先决条件,我们扩展了色运动学对偶从伴随的规范群的基本表示。我们解释了基本运动李代数应满足的分子关系。我们给出了非平凡的证据支持我们的建设使用明确的树和循环振幅,以及更一般的参数。

英文摘要:

We give a prescription for the computation of loop-level scattering amplitudes in pure Einstein gravity, and four-dimensional pure supergravities, using the color-kinematics duality. Amplitudes are constructed using double copies of pure (super-)Yang-Mills parts and additional contributions from double copies of fundamental matter, which are treated as ghosts. The opposite-statistics states cancel the unwanted dilaton and axion in the bosonic theory, as well as the extra matter supermultiplets in supergravities. As a spinoff, we obtain a prescription for obtaining amplitudes in supergravities with arbitrary non-self-interacting matter. As a prerequisite, we extend the color-kinematics duality from the adjoint to the fundamental representation of the gauge group. We explain the numerator relations that the fundamental kinematic Lie algebra should satisfy. We give nontrivial evidence supporting our construction using explicit tree and loop amplitudes, as well as more general arguments.
