An updated version of the PNJL model is used to study the thermody-namics of N f = 2 quark flavors interacting through chiral four-point couplings and propagating in a homogeneous Polyakov loopâ€¦ (More)

We calculate the pion self-energies in asymmetric nuclear matter in the two-loop approximation of chiral perturbation theory. We find three types of corrections beyond the well-known linear densityâ€¦ (More)

This presentation reviews recent guiding themes 2 in the broad context of nuclear physics, from developments in chiral effective field theory applied to nuclear systems, via the phases and structuresâ€¦ (More)

We analyse the baryon mass spectrum in a framework which combines the 1/Nc expansion with chiral perturbation theory. Meson loop contributions involving the full SU(3) octet of pseudoscalar Goldstoneâ€¦ (More)

We study the quark mass expansion of the magnetic moments of the nucleon in a chiral effective field theory including nucleons, pions and delta resonances as explicit degrees of freedom. We point outâ€¦ (More)

QCD-based thermodynamics at zero and finite quark chemical potential is studied using an extended Nambu and Jona-Lasinio approach in which quarks couple simultaneously to the chiral condensate and toâ€¦ (More)

Based on an effective Lagrangian which combines chiral SU(3) dynamics with vector meson dominance, we have developed a model for the forward vector meson-nucleon scattering amplitudes. We use this asâ€¦ (More)

The frequency response of a fiber-optic hydrophone that uses a dielectric multilayer system as the sensing element for ultrasound detection is investigated. A primary interferometric calibrationâ€¦ (More)

We examine the meson-baryon interaction in the strangeness S = âˆ’1 sector using an effective chiral Lagrangian. Potentials are derived from this Lagrangian and used in a coupled-channel calculation ofâ€¦ (More)

We investigate three-colour QCD thermodynamics at finite quark chemical potential. Lattice QCD results are compared with a generalized Nambu JonaLasinio model in which quarks couple simultaneously toâ€¦ (More)
