Constituent-quark model description of triply heavy-baryon nonperturbative lattice QCD data

This paper provides results for the spectra of triply charmed and bottom baryons based on a constituent quark model approach. We take advantage of the assumption that potential models are expected to describe triply heavy baryons to a similar degree of accuracy as the successful results obtained in the charmonium and bottomonium sectors. The high precision calculation of the ground state and po...

Constituent Quark Model versus Nonperturbative QCD

We discuss a few, apparently different (but actually, tightly related) problems: 1. The relation between QCD and valence quark model, 2. The asymptotic behavior of the nonperturbative pion wave function ψ(~k2 ⊥, x) at x → 0, 1, ~k2 ⊥ → ∞ and 3. The dimensional counting rules in the intermediate region of energy. The analysis is based on such general methods as dispersion relations, duality and ...

Constituent Quark Model Approach to Heavy Baryon Transitions

I discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry (HQS) limit as mQ → ∞. By doing a spin-parity analysis I derive a general formula which allows one to enumerate the independent HQS amplitudes in the three types of transitions. I go on to show th...

Baryon Spectroscopy and the Constituent Quark Model

We explore further the idea that the lattice QCD data for hadron properties in the region mπ > 0.2GeV 2 can be described by the constituent quark model. This leads to a natural explanation of the fact that nucleon excited states are generally stable for pion masses greater than their physical excitation energies. Finally we apply these same ideas to the problem of how pentaquarks might behave i...

Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties

So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
