Two-loop form factors for pseudo-scalar quarkonium production and decay
Samuel Abreu, Matteo Becchetti, Claude Duhr +1
We present the analytic expressions for the two-loop form factors for the production or decay of pseudo-scalar quarkonia, in a scheme where the quarks are produced at threshold. We…
Two-loop master integrals for pseudo-scalar quarkonium and leptonium production and decay
Samuel Abreu, Matteo Becchetti, Claude Duhr +1
We compute the master integrals relevant for the two-loop corrections to pseudo-scalar quarkonium and leptonium production and decay. We present both analytic and high-precision nu…
Linear power corrections to shape variables in the three-jet region
Fabrizio Caola, Silvia Ferrario Ravasio, Giovanni Limatola +3
We use an abelian model to study linear power corrections which arise from infrared renormalons and affect event shapes in annihilation into hadrons. While previous studie…
White Paper on Forward Physics, BFKL, Saturation Physics and Diffraction
Martin Hentschinski, Christophe Royon, Marco Alcazar Peredo +39
The goal of this whitepaper is to give a comprehensive overview of the rich field of forward physics. We discuss the occurrences of BFKL resummation effects in special final states…
