A consistent model for πN transition distribution amplitudes and backward pion electroproduction
J. P. Lansberg, B. Pire, K. Semenov-Tian-Shansky +1
The extension of the concept of generalized parton distributions leads to the introduction of baryon to meson transition distribution amplitudes (TDAs), non-diagonal matrix element…
Implications of finite one-loop corrections for seesaw neutrino masses
D. Aristizabal Sierra
In the standard seesaw model, finite corrections to the neutrino mass matrix arise from one-loop self-energy diagrams mediated by a heavy neutrino. We discuss the impact that these…
The role of the running coupling constant in the unveiling of the hadronic structure
A. Courtoy
One of the main open questions in physics is the understanding of the internal structure of the strongly interacting particles, or hadrons. It is still a challenge to describe cons…
One-loop finite corrections to seesaw neutrino masses
D. Aristizabal Sierra
In the standard seesaw model, finite corrections to the neutrino mass matrix arise from one-loop self-energy diagrams mediated by heavy neutrinos. We discuss the impact that these…
Leptogenesis in the presence of exact flavor symmetries
D. Aristizabal Sierra, Federica Bazzocchi
In models with flavor symmetries in the leptonic sector leptogenesis can take place in a very different way compared to the standard leptogenesis scenario. We study the generation…
One particle and Drell-Yan pair associated production
Federico Alberto Ceccopieri
We briefly discuss the collinear factorization formula for the associated production of one particle and a Drell-Yan pair in hadronic collisions. We outline possible applications o…
