Kaon Structure in the Nuclear Medium within the Light Front Approach
G. H. S. O. Yabusaki, J. P. B. C. de Melo, K. Tsushima +2
We study the properties of the charged kaon in symmetric nuclear matter using a Bethe-Salpeter amplitude to model the quark-anti-quark bound state, which is well constrained by pre…
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…
Massless DKP fields in Riemann-Cartan space-times
R. Casana, V. Ya. Fainberg, B. M. Pimentel +2
We study massless Duffin-Kemmer-Petiau (DKP) fields in the context of Einstein-Cartan gravitation theory, interacting via minimal coupling procedure. In the case of an identically…
Spin 1 fields in Riemann-Cartan space-times "via" Duffin-Kemmer-Petiau theory
R. Casana, B. M. Pimentel, J. T. Lunardi +1
We consider massive spin 1 fields, in Riemann-Cartan space-times, described by Duffin-Kemmer-Petiau theory. We show that this approach induces a coupling between the spin 1 field a…
