Two-pion exchange NN potential from Lorentz-invariant EFT
Renato Higa, Manoel R. Robilotta, Carlos A. da Rocha
We outline the progress made in the past five years by the São Paulo group in the development of a two-pion exchange nucleon-nucleon potential within a Lorentz-invariant framework…
Relativistic two-pion exchange nucleon-nucleon potential: parametrized version
R. Higa, M. R. Robilotta, C. A. da Rocha
The chiral two-pion exchange nucleon-nucleon interaction has nowadays a rather firm conceptual basis, but depends on low-energy constants, which may be extracted from fits to data.…
Relativistic two-pion exchange nucleon-nucleon potential: configuration space
Renato Higa, Manoel R. Robilotta, Carlos A. da Rocha
We have recently performed a relativistic chiral expansion of the two-pion exchange potential, and here we explore its configuration space content. Interactions are d…
Scalar-isoscalar mesons in pion production at threshold
Claudio M. Maekawa, Carlos A. da Rocha
We present the contributions of the non-linear chiral scalar field S to cross sections of and reactions at threshold. We compare our res…
The N N -> NN pi+ Reaction near Threshold in a Chiral Power Counting Approach
C. A. da Rocha, G. A. Miller, U. van Kolck
Power-counting arguments are used to organize the interactions contributing to the N N -> d pi, p n pi reactions near threshold. We estimate the contributions from the three formal…
