The Masses of Heavy Pentaquarks in Non-Relativistic Bethe-Salpeter Quark Model
- PhysicsRevista Mexicana de Física
- 2021
The exotic particles such as the pentaquarks are to strengthen understanding of important interactions and the principle of QCD in which pentaquarks contain two heavy- valence quarks. The structure…
Tetraquarks, pentaquarks and dibaryons in the large N QCD
- PhysicsThe European Physical Journal C
- 2018
We study the multiquark hadrons in large N QCD under the ’t-Hooft limit, extending Witten’s picture of the baryons. We explore the decay widths of tetraquarks, pentaquarks and dibaryons. Based on the…
XYZ: four-quark states?
- Physics
- 2015
The observation of many unexpected states decaying into heavy quarkonia has challenged the usual Q-Qbar interpretation. We will discuss the nature of some of the charmonium-like resonances recently…
Constituent quark-model hidden-flavor pentaquarks
- PhysicsPhysical Review D
- 2022
We study hidden-flavor pentaquarks, Q ¯ Qqqq , based on a constituent quark-model with a standard quark-quark interaction that reproduces the low-energy meson and baryon spectra. We make use of…
Possible molecular pentaquark states with different spin and quark configurations
- PhysicsPhysical Review D
- 2018
We investigate three possible pentaquark candidates, one of which contains a single charm quark and the other two contain triple charm quarks in their substructure. To this end we apply the QCD sum…

Properties of the P c(4312) pentaquark and its bottom partner
- Physics
- 2021
We present an analysis of the newly observed pentaquark to shed light on its quantum numbers. To do that, the QCD sum rules approach is used. The measured mass of this particle is close to the…
Narrow pentaquarks as diquark-diquark-antiquark systems
- Physics
- 2017
The diquark-diquark-antiquark model describes pentaquark states both in terms of quarks and hadrons. The latest LHCb data for pentaquarks with open charm emphasize the importance of hadron components…
Baryon Masses and Strangeness Suppression in the Unquenched Quark Model
- PhysicsFew-Body Systems
- 2018
We discuss the latest applications of the Unquenched Quark Model (UQM) to the calculation of baryon observables. In particular, we focus on strangeness suppression effects in baryon-meson…

New look at scalar mesons.
- PhysicsPhysical review letters
- 2004
Light scalar mesons are found to fit rather well a diquark-antidiquark description. The resulting nonet obeys mass formulas which respect, to a good extent, the Okubo-Zweig-Iizuka (OZI) rule. OZI…
Multi-Quark Hadrons. 1. The Phenomenology of (2 Quark 2 anti-Quark) Mesons
- Physics
- 1976
The spectra and dominant decay couplings of Q2Q¯2 mesons are presented as calculated in the quark-bag model. Certain known 0+ mesons [e(700),S*,δ,κ] are assigned to the lightest cryptoexotic Q2Q¯2…
Tetraquark mesons in large-N quantum chromodynamics.
- PhysicsPhysical review letters
- 2013
It is argued that exotic mesons consisting of two quarks and two antiquarks are not ruled out in quantum chromodynamics with a large number N of colors, as generally thought. Tetraquarks of one class…
Diquarks and exotic spectroscopy.
- PhysicsPhysical review letters
- 2003
It is proposed that the recently discovered Theta(+) baryon is a bound state of four quarks and an antiquark, containing two highly correlated ud pairs, and it lies in an near-ideally mixed SU(3)(f) 10;(f) plus sign in circle 8(f).
Z (4430) and a new paradigm for spin interactions in tetraquarks
- Physics
- 2014
Following the recent confirmation of the Z+(4430) resonance with J^{PG}=1^{++}, we have re-examined the model of S- and P-wave tetraquarks. We propose a `type-II' diquark-antidiquark model which…
Hadron Masses in a Gauge Theory
- Physics
- 1975
We explore the implications for hadron spectroscopy of the "standard" gauge model of weak, electromagnetic, and strong interactions. The model involves four types of fractionally charged quarks, each…
Diquark-antidiquarks with hidden or open charm and the nature of X(3872)
- Physics
- 2005
Heavy-light diquarks can be the building blocks of a rich spectrum of states which can accommodate some of the newly observed charmoniumlike resonances not fitting a pure $c\overline{c}$ assignment.…
Dynamical picture for the formation and decay of the exotic XYZ mesons.
- PhysicsPhysical review letters
- 2014
We present a new dynamical picture that identifies the formation of the exotic c[over ¯]c-containing states XYZ with the confinement-induced hadronization of a rapidly separating pair of a compact…
