Baryonic content of the pion
Pablo Sanchez-Puertas, Enrique Ruiz Arriola, Wojciech Broniowski
The baryon form factor of charged pions arises since isospin symmetry is broken with unequal up and down quark masses, , as well as electromagnetic effects. We obtain esti…
NN scattering and nuclear uncertainties
Enrique Ruiz Arriola, Jose Enrique Amaro, Rodrigo Navarro Perez
Ab initio calculations in Nuclear physics for atomic nuclei require a specific knowledge of the interactions among their constituents, protons and neutrons. In particular, NN inter…
Counting states and the Hadron Resonance Gas: Does X(3872) count?
Pablo G. Ortega, David R. Entem, Francisco Fernandez +1
We analyze how the renowned X(3872), a weakly bound state right below the threshold, should effectively be included in a hadronic representation of the QCD partition f…
Signatures of alpha clustering in light nuclei from relativistic nuclear collisions
Wojciech Broniowski, Enrique Ruiz Arriola
We argue that relativistic nuclear collisions may provide experimental evidence of alpha clustering in light nuclei. A light alpha-clustered nucleus has a large intrinsic deformati…
Valence double parton distributions of the nucleon in a simple model
Wojciech Broniowski, Enrique Ruiz Arriola
Valence double parton distribution functions of the nucleon are evaluated in the framework of a simple model, where the conservation of the longitudinal momentum is taken into acco…
Error Analysis of Nuclear Matrix Elements
J. E. Amaro, R. Navarro Perez, E. Ruiz Arriola
We estimate the expected errors of nuclear matrix elements coming from the uncertainty on the NN interaction. We use a coarse grained (GR) interaction fitted to NN scattering data,…
Effective interactions in the delta-shells potential
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
We determine two-body Skyrme force parameters from a Nucleon-Nucleon interaction as a function of the maximal momentum fitting NN scattering data. We find general agreement with Vl…
