Fully Heavy Tetraquark Spectroscopy in the Relativistic Quark Model [PDF]

open access: yesSymmetry, 2022
Masses of the ground and excited (1P, 2S, 1D, 2P, 3S) states of the fully heavy tetraquarks, composed of charm (c) and bottom (b) quarks and antiquarks, are calculated in the diquark–antidiquark picture within the relativistic quark model based on the ...

Heavy Tetraquarks in the Relativistic Quark Model [PDF]

open access: yesUniverse, 2021
We give a review of the calculations of the masses of tetraquarks with two and four heavy quarks in the framework of the relativistic quark model based on the quasipotential approach and QCD.

Relativistic corrections to decays of heavy baryons in the quark model [PDF]

open access: yesPhysical Review D, 2021
We investigate relativistic corrections of an order 1 /m 2 , where m is the constituent quark mass, to heavy baryon decays by emitting one pseudoscalar meson in the quark model.

Tetra- and Penta-Quark Structures in the Constituent Quark Model [PDF]

open access: yesSymmetry, 2020
With the development of high energy physics experiments, a large amount of exotic states in the hadronic sector have been observed. In order to shed some light on the nature of the tetraquark and pentaquark candidates, a constituent quark model, along ...

Tetraquarks and Pentaquarks from Quark Model Perspective

open access: yesSymmetry, 2023
According to the classification of the quark model, the hadrons going beyond three-quark baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons have been observed since 2003, some of which exhibit exotic behaviors.

Coupling Hadron-Hadron Thresholds within a Chiral Quark Model Approach [PDF]

open access: yesSymmetry, 2020
Heavy hadron spectroscopy was well understood within the naive quark model until the end of the past century. However, in 2003, the X(3872) was discovered, with puzzling properties difficult to understand in the simple naive quark model picture.

Masses of fully heavy tetraquarks $$QQ {\bar{Q}} {\bar{Q}}$$ in an extended relativized quark model [PDF]

open access: yes, 2020
Inspired by recent measurement of possible fully charmed tetraquarks in LHCb Collaboration, we investigate the mass spectra of fully heavy tetraquarks $QQ \bar Q \bar Q$ in an extended relativized quark model.

Masses of doubly heavy tetraquarks TQQ′ in a relativized quark model [PDF]

open access: yes, 2020
In the present work, the mass spectra of doubly heavy tetraquarks $T_{QQ^\prime}$ are systematically investigated in a relativized quark model. The four-body systems including the Coulomb potential, confining potential, spin-spin interactions, and ...

Triply heavy baryons in the constituent quark model [PDF]

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2019
The constituent quark model is used to compute the ground and excited state masses of QQQbaryons containing either c or bquarks. The quark model parameters previously used to describe the properties of charmonium and bottomonium states were used in this ...

Excited bottom-charmed mesons in a nonrelativistic quark model [PDF]

open access: yesPhysical Review D, 2019
Using the newly measured masses of ${B}_{c}(1S)$ and ${B}_{c}(2S)$ from the CMS Collaboration and the $1S$ hyperfine splitting determined from the lattice QCD as constraints, we calculate the ${B}_{c}$ mass spectrum up to the $6S$ multiplet with a ...
