Implicit vs Explicit renormalization of the force
Enrique Ruiz Arriola, Sergio Szpigel, Varese Salvador Timoteo
We use an S-wave toy model for the two-nucleon system to show that the implicit renormalization of a contact theory matches the explicit renormalization through a flow equation whi…
Partial Wave Analysis of Chiral NN Interactions
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
We analyze chiral interactions to N2LO on the light of proton-proton and neutron-proton scattering data published from 1950 till 2013 and discuss conditions under which the chiral…
Coarse grained Potential analysis of neutron-proton and proton-proton scattering below pion production threshold
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
Using the delta-shell representation we present a successful fit to neutron-proton and proton-proton scattering data below pion production threshold. A detailed overview of the the…
Fixed points of the Similarity Renormalization Group and the Nuclear Many-Body Problem
E. Ruiz Arriola, S. Szpigel, V. S. Timoteo
The Similarity Renormalization Group reduces the off-shellness by driving the evolved interaction towards a diagonal band. We analyze the infrared limit and the corresponding on-sh…
Coarse grained NN potential with Chiral Two Pion Exchange
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
We determine the chiral constants of the Nucleon-Nucleon Two Pion Exchange potential deduced from Chiral Perturbation Theory. By using a coarse grained representation of the short…
Implicit vs Explicit Renormalization and Effective Interactions
E. Ruiz Arriola, S. Szpigel, V. S. Timoteo
Effective interactions can be obtained from a renormalization group analysis in two complementary ways. One can either explicitly integrate out higher energy modes or impose given…
