A toy model for generalised parton distributions
J. R. Cudell, F. Bissey, J. Cugnon +3
We give the results of a simple model for the diagonal and off-diagonal valence quark distributions of a pion. We show that structure can be implemented in a gauge-invariant manner…
A Simple Model for Generalised Parton Distributions of the Pion
J. P. Lansberg, F. Bissey, J. R. Cudell +2
We present here an extension of our model for the pion, which we used previously to calculate its diagonal structure function, to the off-forward case. The imaginary part of the of…
The Valence Quark Distribution of the Pion
J. P. Lansberg, F. Bissey, J. R. Cudell +3
The pion structure function is investigated in a simple model, where the pion and its constituent quark fields are coupled through the simplest pseudoscalar coupling. The imaginary…
Scalar meson exchange and the baryon spectra
P. Stassart, Fl. Stancu, J. -M. Richard
We explore the role of a scalar meson exchange interaction between quarks in a semirelativistic constituent quark model where the quarks are subject to a linear confinement. We sea…
