Van der Waals forces and Photon-less Effective Field Theories
E. Ruiz Arriola
In the ultra-cold regime Van der Waals forces between neutral atoms can be represented by short range effective interactions. We show that universal low energy scaling features of…
Scalar-isoscalar states, gravitational form factors, and dimension-2 condensates in a large-Nc Regge approach
Enrique Ruiz Arriola, Wojciech Broniowski
Scalar-isoscalar states are analyzed within the large-Nc Regge approach. We find that the lightest f0(600) scalar-isoscalar state fits very well into the pattern of the radial Regg…
Universal low energy features of two-body systems
A. Calle Cordon, E. Ruiz Arriola
We apply renormalization ideas to study low-energy interactions in two-body systems. As we will see this method highlights a model-independent description of a broad variety of sys…
Nucleon-Nucleon interaction, charge symmetry breaking and renormalization
A. Calle Cordon, M. Pavon Valderrama, E. Ruiz Arriola
We study the interplay between charge symmetry breaking and renormalization in the NN system for s-waves. We find a set of universality relations which disentangle explicitly the k…
Transversity relations, chiral and holographic models, and pion wave functions from lattice QCD
Enrique Ruiz Arriola, Wojciech Broniowski
We analyze the equal-time Bethe-Salpeter quark wave functions of the pion in various models. We discuss how the quenched lattice QCD results with delocalized pion interpolators can…
Low scale saturation of Effective NN Interactions and their Symmetries
E. Ruiz Arriola
The Skyrme force parameters can be uniquely determined by coarse graining the NN interactions at a characteristic momentum scale. We show how exact Vlowk potentials to second order…
Pion transition form factor in the Regge approach
Wojciech Broniowski, Enrique Ruiz Arriola
We explore the BaBar puzzle within the Regge approach. After reviewing the chiral quark models in applications to PDF and PDA of the pion, we argue that variants of these models, f…
Renormalization of One Meson Exchange Potentials and Their Currents
A. Calle Cordon, E. Ruiz Arriola
The Nucleon-Nucleon One Meson Exchange Potential, its wave functions and related Meson Exchange Currents are analyzed for point-like nucleons. The leading Nc contributions generate…
Transversity form factors of the pion in chiral quark models
Wojciech Broniowski, Alexander E. Dorokhov, Enrique Ruiz Arriola
The transversity form factors of the pion, involving matrix elements of bilocal tensor currents, are evaluated in chiral quark models, both in the local Nambu--Jona-Lasinio with th…
Renormalization of chiral two pion exchange NN interactions with delta excitations: correlations in the partial wave expansion
M. Pavon Valderrama, E. Ruiz Arriola
In this work we consider the renormalization of the chiral two-pion exchange potential with explicit delta-excitations for nucleon-nucleon scattering at next-to-leading (NLO) and n…
Pion transition form factor in the Regge approach and incomplete vector-meson dominance
Enrique Ruiz Arriola, Wojciech Broniowski
The concept of incomplete vector-meson dominance and Regge models is applied to the transition form factor of the pion. First, we argue that variants of the chiral quark model fulf…
Scalar-isoscalar states in the large-Nc Regge approach
Enrique Ruiz Arriola, Wojciech Broniowski
Scalar-isoscalar states (0++) are investigated within the large-Nc Regge approach. We elaborate on the consequences of including the lightest f0(600) scalar-isoscalar state into su…
Isospin breaking effects in the dynamical generation of the X(3872)
D. Gamermann, J. Nieves, E. Oset +1
We have studied isospin breaking effects in the X(3872) resonance and found a natural explanation for the branching fraction of the X decaying to with two and three pions bei…
