On the Equivalence of Three-Particle Scattering Formalisms
A. W. Jackura, S. M. Dawid, C. Fernández-Ramírez +5
In recent years, different on-shell scattering formalisms have been proposed to be applied to both lattice QCD and infinite volume scattering processes. W…
Kaluza-Klein reduction on a maximally non-Riemannian space is moduli-free
Kyoungho Cho, Kevin Morand, Jeong-Hyuck Park
We propose a novel Kaluza-Klein scheme which assumes the internal space to be maximally non-Riemannian, meaning that no Riemannian metric can be defined for any subspace. Its descr…
Structure of Pion Photoproduction Amplitudes
V. Mathieu, J. Nys, C. Fernandez-Ramirez +5
We derive and apply the finite energy sum rules to pion photoproduction. We evaluate the low energy part of the sum rules using several state-of-the-art models. We show how the dif…
Global analysis of charge exchange meson production at high energies
JPAC Collaboration, J. Nys, A. N. Hiller Blin +7
Many experiments that are conducted to study the hadron spectrum rely on peripheral resonance production. Hereby, the rapidity gap allows the process to be viewed as an independent…
