Stability of the pentaquark in a naive string model

The pentaquark is studied in a simple model of confinement in which the quarks and the antiquark are linked by flux tubes of minimal cumulated length and the Coulomb-like interaction, the…

Precise determination of the three-quark potential in SU(3) lattice gauge theory

We investigate the static interquark potential for the three-quark system in SU(3) lattice gauge theory at zero temperature by using Monte Carlo simulations. We extract the potential from the…

Hall–Post inequalities: Review and application to molecules and tetraquarks

Four-Quark Stability

The physics of charm has become one of the best laboratories exposing the limitations of the naive constituent quark model and also giving hints into a more mature description of meson spectroscopy,…

The Interplay between Compact and Molecular Structures in Tetraquarks

Due to the cluster reducibility of multiquark operators, a strong interplay exists in tetraquarks between the compact structures, resulting from the direct confining forces acting on quarks and…

An introduction to the quark model

This document contains a review on the quark model, prepared for lectures at the Niccolo Cabeo School at Ferrara in May 2012. It includes some historical aspects, the spectral properties of the…

Non-Abelian Dynamics and Heavy Multiquarks

A brief review is first presented of attempts to predict stable multiquark states within current models of hadron spectroscopy. Then a model combining flip–flop and connected Steiner trees is…

Fully Heavy Multiquarks

The existence of stable multiquarks made of heavy quarks and antiquarks is discussed in the framework of potential models. It is stressed that the few-body problem should be handled seriously and…

Molecular and compact four-quark states

We study charmonium (cn), bottomonium (bn) and exotic (cc and bb) four-quark states by means of a standard non-relativistic quark potential model. We look for possible bound states. Among them we are…

Hyperspherical variables analysis of lattice QCD three-quark potentials: skewed Y-string as the mechanism of confinement?

We have re-analysed the lattice QCD calculations of the 3-quark potentials by: (i) Sakumichi and Suganuma (Phys Rev D 92(3), 034511, 2015); and (ii) Koma and Koma (Phys Rev D 95(9), 094513, 2017)…

Stability of multiquarks in a simple string model

A simple string model inspired by the strong-coupling regime of quantum chromodynamics is used as a potential for studying the spectrum of multiquark systems with two quarks and two antiquarks, with…

QCD string in mesons and baryons

AbstractThe distributions of fields generated by static $$Q\bar Q$$ and QQQ sources are calculated analytically within the bilocal approximation of the method of vacuum correlation functions. At…

Detailed analysis of the tetraquark potential and flip-flop in SU(3) lattice QCD

We perform the detailed study of the tetraquark (4Q) potential V{sub 4Q} for various QQ-QQ systems in SU(3) lattice QCD with {beta}=6.0 and 16{sup 3}x32 at the quenched level. For about 200 different…

Absence of exotic hadrons in flux-tube quark models.

In this limit of small coupling between different flux-tube topologies, it is shown that no bound exotic states exist, in contrast with predictions made with bag and other mean-field and two-body potential quark models.

Three-Quark Potential in SU(3) Lattice QCD.

The static three-quark ( 3Q) potential is studied in SU(3) lattice QCD with 12( 3)x24 and beta = 5.7 at the quenched level and a universal feature of the string tension, sigma(3Q) approximately s Sigma(Q&Qmacr;), and the OGE result for Coulomb coefficients, A(3 Q) approximately 1 / 2A(Q & Qmacr).

Multiquark interactions in the strong-coupling expansion of lattice gauge theories

We show that the strong-coupling expansion of lattice gauge theories leads to static multiquark interactions which are in contrast to the additive-potential model and avoid the difficulties of this…
