We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

We present a novel analysis of the π N scattering amplitude in Lorentz covariant baryon
chiral perturbation theory renormalized in the extended-on-mass-shell scheme. This …

Chiral perturbation theory and its unitarized versions have played an important role in our
understanding of the low-energy strong interaction. Yet, so far, such studies typically deal …

Baryon chiral perturbation theory (BChPT), as an effective field theory of low-energy
quantum chromodynamics (QCD), has played and is still playing an important role in our …

We revisit the classical relation between the strangeness content of the nucleon, the pion–
nucleon sigma term and the SU (3) F breaking of the baryon masses in the context of …

The Born cross sections of the e+ e−→ Σ+ Σ¯− and e+ e−→ Σ− Σ¯+ processes are
determined for center-of-mass energy from 2.3864 to 3.0200 GeV with the BESIII detector …

Dark sector particles at the GeV scale carrying baryon number provide an attractive
framework for understanding the origin of dark matter and the matter-antimatter asymmetry …

We construct a relativistic chiral nucleon-nucleon interaction up to the next-to-next-to-
leading order in covariant baryon chiral perturbation theory. We show that a good …

We present a novel analysis of the π N scattering amplitude in covariant baryon chiral
perturbation theory up to O (p 3) within the extended-on-mass-shell renormalization scheme …

The Born cross sections of e+ e−→ Σ 0 Σ¯ 0 are measured at center-of-mass energies from
2.3864 to 3.0200 GeV using data samples with an integrated luminosity of 328.5 pb− 1 …
