Tensor decomposition of $e^{+} e^{-} \to π^{+} π^{-} γ$ to higher orders in the dimensional regulator

Thomas Dave, Jérémy Paltrinieri, Pau Petit Rosàs +1

We present a first study of the scattering process $e^{+} e^{-} \to π^{+} π^{-} γ$ beyond next-to-leading order, aimed at providing preliminary insights required for future NNLO predictions fo…

Radiative return meets GVMD

Pau Petit Rosàs, Olga Shekhovtsova, William J. Torres Bobadilla

We improve the description of pion-photon interactions in the radiative return process $e^{+} e^{-} \to π^{+} π^{-} γ$ at the next-to-leading order by including the pion form factor in the Fey…

Evaluation of Feynman integrals via numerical integration of differential equations

Pau Petit Rosàs

We revisit the idea of numerically integrating the differential form of Feynman integrals. With a novel approach for the treatment of branch cuts, we develop an integrator capable…
