The mixed quark-gluon condensate from an effective quark-quark interaction [PDF]

, 1997
We exhibit the method for obtaining non perturbative quark and gluonic vacuum condensates from a model truncation of QCD. The truncation allows for a phenomenological description of the quark-quark interaction in a framework which maintains all global ...

The Short Range Mechanism of N-N interaction in the Extended Chiral SU(3) Quark Model [PDF]

, 2004
We give the comparisons between the chiral SU(3) quark model and the extended chiral SU(3) quark model. The results show that the phase shifts of NN scattering are very similar.

N-N Interactions in the Extended Chiral SU(3) Quark Model

, 2003
The chiral SU(3) quark model is extended to include coupling between vector chiral field and quarks. By using this model, the phase shifts of NN scattering for different partial waves are studied. The results are very similar to those of the chiral SU(3)

Unified framework for generalized and transverse-momentum dependent parton distributions within a 3Q light-cone picture of the nucleon [PDF]

, 2011
We present a systematic study of generalized transverse-momentum dependent parton distributions (GTMDs). By taking specific limits or projections, these GTMDs yield various transverse-momentum dependent and generalized parton distributions, thus ...

Quark Number Fluctuations in a Chiral Model at Finite Baryon Chemical Potential

, 2007
We discuss the net quark and isovector fluctuations as well as off-diagonal quark flavor susceptibilities along the chiral phase transition line in the Nambu--Jona-Lasinio (NJL) model.

Calculation of some properties of the vacuum [PDF]

, 2002
In this article, we calculate the dressed quark propagator with the flat bottom potential in the framework of the rain-bow Schwinger-Dyson equation, which is determined by mean field approximation of the global colour model lagrangian.

The Quark Orbital Angular Momentum in a Light-Cone Representation

, 1998
We perform an analysis of the quark angular momentum in a light-cone representation by taking into account the effect due to the Melosh-Wigner rotation and find that there is a relativistic correction factor connecting the quark orbital angular momentum ...

Phenomenological study of hadron interaction models [PDF]

, 2001
We present a phenomenological study of three models with different effective degrees of freedom: a Goldstone Boson Exchange (GBE) model which is based on quark-meson couplings, the quark delocalization, color screening model (QDCSM) which is based on ...

Unquenching the Quark Model

, 2007
We present the formalism for a new generation of unquenched quark models in which quark-antiquark pair effects are taken into account in an explicit form via a microscopic QCD-inspired quark-antiquark creation mechanism. No truncation in the sum over all

The unquenched quark model

, 2015
In this contribution, we briefly discuss the results for charmonium and bottomonium spectra with self-energy corrections in the unquenched quark model, due to the coupling to the meson-meson continuum.
