Conformal Gravity from Gauge Theory
Henrik Johansson, Josh Nohle
We use the duality between color and kinematics to obtain scattering amplitudes in non-minimal conformal N=0,1,2,4 (super)gravity theories. Generic tree amplitudes can be construct…
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…
On Loop Corrections to Subleading Soft Behavior of Gluons and Gravitons
Zvi Bern, Scott Davies, Josh Nohle
Cachazo and Strominger recently proposed an extension of the soft-graviton theorem found by Weinberg. In addition, they proved the validity of their extension at tree level. This w…
Low-Energy Behavior of Gluons and Gravitons from Gauge Invariance
Zvi Bern, Scott Davies, Paolo Di Vecchia +1
We show that at tree level, on-shell gauge invariance can be used to fully determine the first subleading soft-gluon behavior and the first two subleading soft-graviton behaviors.…
Color-Kinematics Duality in One-Loop Four-Gluon Amplitudes with Matter
Josh Nohle
Four-point one-loop nonsupersymmetric pure Yang-Mills amplitudes with the duality between color and kinematics manifest have been constructed in previous work. Here, we extend the…
Color-Kinematics Duality for Pure Yang-Mills and Gravity at One and Two Loops
Zvi Bern, Scott Davies, Tristan Dennen +2
We provide evidence in favor of the conjectured duality between color and kinematics for the case of nonsupersymmetric pure Yang-Mills amplitudes by constructing a form of the one-…
