Alpha-alpha interaction with chiral two pion exchange and 8Be lifetime
E. Ruiz Arriola
Assuming that alpha particles are described by a scalar-isoscalar chiral invariant heavy field it is shown how chiral symmetry determines the alpha-alpha interaction at long distan…
Renormalizing the Schrodinger Equation for NN scattering
E. Ruiz Arriola, A. Calle Cordon, M. Pavon Valderrama
The renormalization of the Schr"odinger equation with regular One Boson Exchange and singular chiral potentials including One and Two-Pion exchanges is analyzed within the context…
Large-Nc Regge models and the <A^2> condensate
Wojciech Broniowski, Enrique Ruiz Arriola
We explore the role of the <A^2> gluon condensate in matching Regge models to the operator product expansion of meson correlators.
Renormalization of chiral two-pion exchange NN interactions. Momentum vs. coordinate space
D. R. Entem, E. Ruiz Arriola, M. Pavon Valderrama +1
The renormalization of the chiral np interaction in the 1S0 channel to N3LO in Weinberg counting for the long distance potential with one single momentum and energy independent cou…
Renormalization of NN Interaction with Relativistic Chiral Two Pion Exchange
R. Higa, M. Pavon Valderrama, E. Ruiz Arriola
The renormalization of the NN interaction with the Chiral Two Pion Exchange Potential computed using relativistic baryon chiral perturbation theory is considered. The short distanc…
Renormalization Group Analysis of Boundary Conditions in Potential Scattering
M. Pavon Valderrama, E. Ruiz Arriola
We analyze how a short distance boundary condition for the Schrodinger equation must change as a function of the boundary radius by imposing the physical requirement of phase shift…
