Central Nucleon-Nucleon Potential and Chiral Scalar Form Factor
M. R. Robilotta
The central two-pion exchange NN potential at large distances is studied in the framework of relativistic chiral symmetry and related directly to the nucleon scalar form factor, wh…
Nucleon-nucleon interaction in the Skyrme model
Isabela P. Cavalcante, Manoel R. Robilotta
We consider the interaction of two skyrmions in the framework of the sudden approximation. The widely used product ansatz is investigated. Its failure in reproducing an attractive…
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…
Nucleon-nucleon interaction: Central potential and pion production
C. M. Maekawa, J. C. Pupin, M. R. Robilotta
We show that the tail of the chiral two-pion exchange nucleon-nucleon potential is proportional to the scalar form factor and discuss how it can be translated into effective s…
