Spectrum of the Y=2 pentaquarks
TLDR
Based on an assumed mass formula for the spectrum of the Y=2 pentaquarks, where the chromo-magnetic interaction plays an important role, and identifying the lightest state with the Θ+(1540), the authors predict a spectrum in good agreement with the few I=0 and I=1 candidates proposed in the past.Abstract:

Search for charmed pentaquarks in high energy anti-neutrino interactions
TL;DR: In this paper, the existence of a bound state of five quarks with c ¯ content is still controversial, and the authors focus on weakly decaying charmed pentaquarks and show how they can be searched for in high energy anti-neutrino interactions.

Spectrum of the pentaquarks and selection rules for their decays
TL;DR: By assuming that the chromo-magnetic interaction plays the main role for the mass splittings of the positive and negative parity pentaquarks, the authors predict the mass difference between the lowest Y = 2, I = 0 and I = 1 states in good agreement with the present experimental evidence.

TL;DR: This biennial Review summarizes much of Particle Physics using data from previous editions, plus 2205 new measurements from 667 papers, and features expanded coverage of CP violation in B mesons and of neutrino oscillations.

A Unified Field Theory of Mesons and Baryons
TL;DR: In this article, the structure of the particle source in the classical theory is calculated, and some qualitative features of the interactions between these particles and mesons are described, and the way in which a non-linear meson field theory of this type may contain its own sources, and how these may be idealised to point singularities, as in the conventional field theories of interacting linear systems, is formulated.

Static Properties of Nucleons in the Skyrme Model
TL;DR: In this paper, the static properties of baryons in an SU(2) × SU (2) chiral theory (the Skyrme model) whose solitons can be interpreted as the Baryons of QCD were derived.

Hadron Masses in a Gauge Theory
TL;DR: In this paper, the authors explore the implications for hadron spectroscopy of the "standard" gauge model of weak, electromagnetic, and strong interactions, and use the asymptotic freedom of the model to argue that for the calculation of hadron masses, the short-range quark-quark interaction may be Coulomblike.

Current Algebra, Baryons, and Quark Confinement
TL;DR: In this paper, it was shown that ordinary baryons can be understood as solitons in current algebra effective lagrangians, and that the formation of color flux tubes can also be seen under certain conditions.
