Massive quarks and the quark-parton model

Physical Review D, 1974
The parton-model result $\ensuremath{\nu}{W}_{2}(x)=\ensuremath{\Sigma}{i}^{}{{e}_{i}}^{2}x{f}_{i}(x)$ is derived for massive quarks in the case where partons are identified as quarks. A simple model of a bound-quark system is also given in order to illuminate the ideas behind the derivation.

Ideal quarks and mesons in the relativistic quark model

Physical Review C, 1994
We propose a microscopic theory for interacting mesons and ideal quarks in the relativistic quark model using the time-dependent mean-field theory technique. For simplicity we examined the Nambu--Jona-Lasinio model. The dynamical chiral-symmetry breaking leads to a zero-frequency mode (pion) due to the restoration of chiral symmetry.

A Model of Lepton and Quark Structure

, 2019
We propose a model of particles with two very massive fundamental constituents, maxons. One of them is a fractionally charged color triplet and the other is neutral color singlet.

Nucleon and flavor form factors in a light front quark model in AdS/QCD

, 2013
Using the light front wave functions for the nucleons in a quark model in AdS/QCD, we calculate the nucleon electromagnetic form factors. The flavor decompositions of the nucleon form factors are calculated from the GPDs in this model.
