An exact solution to the Bertsch problem and the non-universality of the Unitary Fermi Gas
E. Ruiz Arriola, S. Szpigel, V. S. Timoteo
We analyze the universality of the Unitary Fermi Gas in its ground state from a Wilsonian renormalization point of view and compute the effective range dependence of the Bertsch pa…
Fitting and selecting scattering data
Enrique Ruiz Arriola, Jose Enrique Amaro, Rodrigo Navarro Perez
The main purpose of scattering experiments is to unveil the underlying structure of the colliding particles and their interaction. Typically one measures scattering observables (cr…
Does count?
Pablo G. Ortega, Enrique Ruiz Arriola
The question on whether or not weakly bound states should be effectively incorporated in a hadronic representation of the QCD partition function is addressed by analyzing the examp…
Thermodynamic characterizations of exotic and missing states
Eugenio Megias, Enrique Ruiz Arriola, Lorenzo Luis Salcedo
Thermal shifts and fluctuations at finite temperature below the deconfinement crossover of QCD from hadronic matter to the Quark-Gluon Plasma provide a viable way to look for exoti…
Partonic quasi-distributions of the proton and pion from transverse-momentum distributions
Wojciech Broniowski, Enrique Ruiz Arriola
The parton quasi-distribution functions (QDFs) of Ji have been found by Radyushkin to be directly related to the transverse momentum distributions (TMDs), to the pseudo-distributio…
Fermi-momentum dependence of relativistic effective mass below saturation from superscaling of quasielastic electron scattering
V. L. Martinez-Consentino, I. Ruiz Simo, J. E. Amaro +1
The relativistic effective mass , and Fermi momentum, , are important ingredients in the determination of the nuclear equation of state, but they have rarely been extract…
Nonperturbative partonic quasidistributions of the pion from chiral quark models
Wojciech Broniowski, Enrique Ruiz Arriola
We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the…
Coarse graining the Bethe-Goldstone equation: nucleon-nucleon high momentum components
I. Ruiz Simo, R. Navarro Perez, J. E. Amaro +1
The delta-shell representation of the nuclear force allows a simplified treatment of nuclear correlations. We show how this applies to the Bethe-Goldstone equation as an integral e…
Hollowness in pp scattering at the LHC
Wojciech Broniowski, Enrique Ruiz Arriola
We examine how the effect of hollowness in pp scattering at the LHC (minimum of the inelasticity profile at zero impact parameter) depends on modeling of the phase of the elastic s…
Excited Hadrons and Quark-Hadron Duality
E. Ruiz Arriola, P. Masjuan, W. Broniowski
We review how Quark-Hadron Duality (QHD) for (u,d) flavors at high energies and in the scaling regime suggests a radial and angular behaviour of mesonic and baryonic resonance mass…
Regge trajectories of Excited Baryons, quark-diquark models and quark-hadron duality
Pere Masjuan, Enrique Ruiz Arriola
The parton model relations in conjunction with quark-hadron duality in deep inelastic scattering suggests an asymptotic dominance of quark-diquark type of baryonic excited states w…
Coarse graining of NN inelastic interactions up to 3 GeV:Repulsive vs Structural core
P. Fernandez-Soler, E. Ruiz Arriola
The repulsive short distance core is one of the main paradigms of nuclear physics which even seems confirmed by QCD lattice calculations. On the other hand nuclear potentials at sh…
Low energy peripheral scaling in Nucleon-Nucleon Scattering and uncertainty quantification
I. Ruiz Simo, J. E. Amaro, E. Ruiz Arriola +1
We analyze the peripheral structure of the nucleon-nucleon interaction for LAB energies below 350 MeV. To this end we transform the scattering matrix into the impact parameter repr…
Hollowness in pp scattering
Wojciech Broniowski, Enrique Ruiz Arriola
It is argued that the hollowness effect (depletion in the absorptive part of the scattering cross section at small values of the impact parameter) in the proton-proton scattering a…
Workshop on Excited Hyperons in QCD Thermodynamics at Freeze-Out (YSTAR2016) Mini-Proceedings
P. Alba, M. Amaryan, V. Begun +38
This Workshop brought top experts, researchers, postdocs, and students from high-energy heavy ion interactions, lattice QCD and hadronic physics communities together. YSTAR2016 dis…
Superscaling analysis of quasielastic electron scattering with relativistic effective mass
J. E. Amaro, E. Ruiz Arriola, I. Ruiz Simo
We provide a parametrization of a new phenomenological scaling function obtained from a chi-square fit to a selected set of (e,e') cross section data expanding a band centered arou…
