Brief history of the pion-nucleon sigma term
J. M. Alarcón
The pion-nucleon sigma term is a quantity involved in many important aspects of particle and nuclear physics. In this review I show its origin and how it is connected to important…
Baryon masses and σ-terms in SU(3) BChPT x 1/Nc
I. P. Fernando, J. M. Alarcon, J. L. Goity
Baryon masses and nucleon σ-terms are studied with the effective theory that combines the chiral and 1/Nc expansions for three flavors. In particular the connection between the dev…
Exploring hyperon structure with electromagnetic transverse densities
Jose Manuel Alarcón, Astrid N. Hiller Blin, Manuel J. Vicente Vacas +1
We explore the structure of the spin-1/2 flavor-octet baryons (hyperons) through their electromagnetic transverse densities. The transverse densities describe the distribution of c…
Transverse densities of octet baryons from chiral effective field theory
Jose Manuel Alarcón, Astrid N. Hiller Blin, C. Weiss
Transverse densities describe the distribution of charge and current at fixed light-front time and provide a frame-independent spatial representation of hadrons as relativistic sys…
Nuclear binding near a quantum phase transition
Serdar Elhatisari, Ning Li, Alexander Rokash +10
How do protons and neutrons bind to form nuclei? This is the central question of ab initio nuclear structure theory. While the answer may seem as simple as the fact that nuclear fo…
Improved description of the pion-nucleon scattering phenomenology in covariant baryon chiral perturbation theory
Jose Manuel Alarcón
We highlight some of the recent advances in the application of chiral effective field theory (chiral EFT) with baryons to the scattering process. We recall some problems that…
