Vector-axial vector lattice cross section and valence parton distribution in the pion from a chiral quark model
Wojciech Broniowski, Enrique Ruiz Arriola
Within a chiral quark model, we evaluate the good cross section in the Euclidean space in the vector - axial vector channel, proposed recently by Ma and Qiu as means to extract the…
Spectral-shift and scattering-equivalent Hamiltonians on a coarse momentum grid
María Gómez-Rocha, Enrique Ruiz Arriola
The solution of the scattering problem based on the Lippmann-Schwinger equation requires in many cases a discretization of the spectrum in the continuum which does not respect the…
Generalized Valon Model for Double Parton Distributions
Wojciech Broniowski, Enrique Ruiz Arriola, Krzysztof Golec-Biernat
We show how the double parton distributions may be obtained consistently from the many-body light-cone wave functions. We illustrate the method on the example of the pion with two…
Phenomenological High Precision Neutron-Proton Delta-Shell Potential
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
We provide a successful fit for proton-neutron scattering below pion production threshold up to LAB energies of 350 MeV. We use seven high-quality fits based on potentials with dif…
Scalar meson mass from renormalized One Boson Exchange Potential
A. Calle Cordon, E. Ruiz Arriola
We determine the mass and strength of the scalar meson from NN scattering data by renormalizing the One Boson Exchange Potential. This procedure provides a great insensitivity to t…
Relativistic NJL Model with Light and Heavy Quarks
A. L. Mota, E. Ruiz Arriola
We study the Nambu-Jona-Lasinio model with light and heavy quarks in a relativistic approach. We emphasize relevant regularization issues as well as the transition from light to he…
