Pinching rules in the chiral-splitting description of one-loop string amplitudes
Filippo Maria Balli, Alex Edison, Oliver Schlotterer
Loop amplitudes in string theories reduce to those of gauge theories and (super)gravity in their worldline description as the inverse string tension tends to zero. The appeara…
Manifest colour-kinematics duality and double-copy in the string-based formalism
Naser Ahmadiniaz, Filippo Maria Balli, Olindo Corradini +3
The relation for the gravity polarisation tensor as the tensor product of two gluon polarisation vectors has been well-known for a long time, but a version of this relation for mul…
Color-kinematics duality from the Bern-Kosower formalism
Naser Ahmadiniaz, Filippo Maria Balli, Cristhiam Lopez-Arcos +2
Berends-Giele currents are fundamental building blocks for on-shell amplitudes in non-abelian gauge theory. We present a novel procedure to construct them using the Bern-Kosower fo…
Compton-like scattering of a scalar particle with N photons and one graviton
Naser Ahmadiniaz, Filippo Maria Balli, Olindo Corradini +2
Tree-level scattering amplitudes for a scalar particle coupled to an arbitrary number N of photons and a single graviton are computed. We employ the worldline formalism as the main…
