New soft theorems for the gravity dilaton and the Nambu-Goldstone dilaton at subsubleading order
Paolo Di Vecchia, Raffaele Marotta, Matin Mojaza +1
We study the soft behavior of two seemingly different particles that are both referred to as dilatons in the literature, namely the one that appears in theories of gravity and in s…
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…
