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…
Peripheral NN scattering from subtractive renormalization of chiral interactions
Edilson Ferreira Batista, Sergio Szpigel, Varese Salvador Timoteo
We apply five subtractions in the Lippman-Schwinger (LS) equation in order to perform a non-perturbative renormalization of chiral N3LO nucleon-nucleon interactions. Here we comput…
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…
Nuclear Symmetries of the similarity renormalization group for nuclear forces
E. Ruiz Arriola, V. S. Timoteo, S. Szpigel
We review the role played by long-distance symmetries within the context of the similarity renormalization group approach. This is based on phase-shift-preserving continuous unitar…
