Quark Condensate in the Deuteron
J-L. Ballot, M. Ericson, M. R. Robilotta
We study the changes produced by the deuteron on the QCD quark condensate by means the Feynman-Hellmann theorem and find that the pion mass dependence of the pion-nucleon coupling…
NN Scattering: Chiral Predictions for Asymptotic Observables
Jean-Louis Ballot, Manoel R. Robilotta, Carlos A. da Rocha
We assume that the nuclear potential for distances larger than 2.5 fm is given just by the exchanges of one and two pions and, for the latter, we adopt a model based on chiral symm…
The role of chiral symmetry in two-pion exchange nuclear potential
C. A. da Rocha, M. R. Robilotta, J. L. Ballot
We evaluate the two pion exchange contribution to the nucleon-nucleon potential in configuration space using a "minimal chiral model" containing only pions and nucleons. We argue t…
TWO-PION EXCHANGE NUCLEAR POTENTIAL - CHIRAL CANCELLATIONS
J-L. Ballot, M. R. Robilotta, C. A. da Rocha
We show that chiral symmetry is responsible for large cancellations in the two-pion exchange nucleon-nucleon interaction, which are similar to those occuring in free pion-nucleon s…
