Meson-Meson Interactions and Resonances in the 't Hooft Model
Z. Batiz, M. T. Pena, A. Stadler
We studied meson-meson interactions using the 't Hooft model, which represents QCD in 1+1 dimensions and assumes a large number of colors (). The dominant interactions in this…
Pion re-scattering in pi0 production
V. Malafaia, M. T. Pena
This work discusses the approximations frequently used to calculate the contribution to pion production in proton-proton scattering near threshold from irreducible pion re-scatteri…
Electromagnetic interactions of three-body systems in the covariant spectator theory
Franz Gross, Alfred Stadler, M. T. Pena
We derive a complete Feynman diagram expansion for the elastic form factor and the three-body photo and electrodisintegration of the three-body bound state using the covariant spec…
Short-range three-nucleon forces and low-energy constants
J. Adam, M. T. Pena, A. Stadler
The 3N forces due to pi-rho, pi-sigma and pi-omega exchanges following from the nucleon Born diagrams and diagrams with an intermediate N^{*}(1440) are re-analyzed. The cancellatio…
Pion re-scattering in pi0 production near threshold
V. Malafaia, M. T. Pena
We compare the most used approximations to calculate the contribution from pion re-scattering mechanisms to pion production from proton-proton scattering, near threshold. Our calcu…
