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…
Ambiguities in the calculation of leptonic decays of excited heavy quarkonium
J. P. Lansberg
We point out that the determination of the leptonic decay width of radially-excited quarkonia is strongly dependent on the position of the node typical of these excitations. We sug…
Quarkonium Production at High-Energy Hadron Colliders
J. P. Lansberg
This thesis can be divided into several parts. The first one consists in a detailed historical review of quarkonium physics, centered on the different production models successivel…
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…
Heavy quarkonium production in hadronic collisions
J. P. Lansberg
Different theoretical models which attempt to describe hadronic production of heavy quarkonia are reviewed. Firstly, we consider the Color Singlet Model and point out the large dis…
