LHCb pentaquarks in constituent quark models

TLDR
The recently discovered P c ( 4380 ) + and P c( 4450 ) + states at LHCb have masses close to the D ¯ Σ c and D ¯ ⁎ Σc thresholds, respectively, which suggest that they may have significant meson-baryon molecular components as mentioned in this paper.

Hadronic molecules

TL;DR: In this article, the authors review experimental evidences of various candidates of hadronic molecules, and methods of identifying such structures Nonrelativistic effective field theories are the suitable framework for studying hadronic molecule, and are discussed in both the continuum and finite volumes.

Pentaquark and Tetraquark states

TL;DR: Recently, the LHCb collaboration not only confirmed the existence of the hidden-charm pentaquarks, but also provided strong evidence of the molecular picture as discussed by the authors, where the authors reviewed the experimental and theoretical efforts on the hidden heavy flavor multiquark systems in the past three years.

A Schematic Model of Baryons and Mesons

TL;DR: In this article, the authors assume that the strong interactions of baryons and mesons are correctly described in terms of the broken "eightfold way", and they are tempted to look for some fundamental explanation of the situation.

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.

The hidden-charm pentaquark and tetraquark states

TL;DR: Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model as discussed by the authors, and investigated various theoretical interpretations of these candidates of the multiquark states.

TL;DR: In this article, the pentaquark-charmonium states were observed in the J/ψp channel in Λ0b→J/K−p decays and the significance of these resonances is more than 9 standard deviations.
