Double-Copy Constructions and Unitarity Cuts
Zvi Bern, Scott Davies, Josh Nohle
The duality between color and kinematics enables the construction of multiloop gravity integrands directly from corresponding gauge-theory integrands. This has led to new nontrivia…

Evanescent Effects Can Alter Ultraviolet Divergences in Quantum Gravity without Physical Consequences
Zvi Bern, Clifford Cheung, Huan-Hang Chi +3
Evanescent operators such as the Gauss-Bonnet term have vanishing perturbative matrix elements in exactly D=4 dimensions. Similarly, evanescent fields do not propagate in D=4; a th…
