Light-by-light scattering at three loops in massless QCD and QED: amplitudes and cross sections
Piotr Bargiela, Amlan Chakraborty, Giulio Gambuti +1
We present the calculation of three-loop massless QCD and QED helicity amplitudes for light-by-light scattering. We make use of Lorentz tensor decomposition in the 't Hooft-Veltman…
Two-loop form factors for -wave quarkonium production and decay
Melih A. Ozcelik
We present the analytical results for the two-loop form factors needed for production and decay. We consider the two-loop corrections to the process $γγ\leftrightarrow…
Prospective report of the French QCD community to the ESPPU 2025 with respect to the program of the LHC Run 5 and beyond and future colliders at CERN
Carolina Arata, François Arleo, Benjamin Audurier +59
This document summarizes the prospective physics plans of the French QCD and Heavy-Ion community, including the experimental programs at the LHC Run 5 and beyond and future collide…
Linear power corrections to single top production and decay at the LHC in the narrow width approximation
Sergei Makarov, Kirill Melnikov, Paolo Nason +1
We consider top quark production and decay in the narrow width approximation and study if the polarisation effects, that manifest themselves in correlations of angular distribution…
