Tensor decomposition of $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I^^{3}$ to higher orders in the dimensional regulator

Thomas Dave, JÃ©rÃ©my Paltrinieri, Pau Petit RosÃ s +1

We present a first study of the scattering process $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I^^{3}$ beyond next-to-leading order, aimed at providing preliminary insights required for future NNLO predictions…

Radiative return meets GVMD

Pau Petit RosÃ s, Olga Shekhovtsova, William J. Torres Bobadilla

We improve the description of pion-photon interactions in the radiative return process $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I^^{3}$ at the next-to-leading order by including the pion form factor in the…

Evaluation of Feynman integrals via numerical integration of differential equations

Pau Petit RosÃ s

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…

Radiative corrections and Monte Carlo tools for low-energy hadronic cross sections in $e^{+} e^{-}$ collisions

Riccardo Aliberti, Paolo Beltrame, Ettore Budassi +32

We present the results of Phase I of an ongoing review of Monte Carlo tools relevant for low-energy hadronic cross sections. This includes a detailed comparison of Monte Carlo code…
