HIGHLIGHTS
- who: Zvi Bern et al. from the Department, Geneva, Switzerland University of have published the research work: Double-copy constructions and unitarity cuts, in the Journal: (JOURNAL)
- what: The authors show by example how one can alleviate difficulties encountered at the multiloop level by relaxing the color-kinematics duality conditions to hold manifestly only on unitarity cuts instead of globally on loop integrands. The authors explore a different strategy for improving the ability to construct multiloop gravity amplitudes. The authors show that once the authors relax BCJ duality constraints so that they are manifest only . . .
