Mirror versus naive assignment in chiral models for the nucleon
Susanna Gallas, Francesco Giacosa
In the framework of chiral model(s) based on the linear realization of chiral symmetry, we investigate the low-energy phenomenological properties of the nucleon and its chiral part…
Nuclear matter within a dilatation-invariant parity doublet model: the role of the tetraquark at nonzero density
Susanna Gallas, Francesco Giacosa, Giuseppe Pagliara
We investigate the role of a scalar tetraquark state for the description of nuclear matter within the parity doublet model in the mirror assignment. In the dilatation-invariant ver…
Vacuum phenomenology of the chiral partner of the nucleon in a linear sigma model with vector mesons
Susanna Gallas, Francesco Giacosa, Dirk H. Rischke
We investigate a linear sigma model with global chiral symmetry. The mesonic degrees of freedom are the standard scalar and pseudoscalar mesons and the v…
The chiral partner of the nucleon in the mirror assignment with global symmetry
Susanna Gallas, Francesco Giacosa, Dirk H. Rischke
We calculate the pion-nucleon scattering lengths and the mass parameter , which describes the nucleon mass in the chiral limit, at tree-level in the framewor…
