Estimates for non-leading distribution functions
R. Jakob, P. J. Mulders, J. Rodrigues
Estimates for leading and non-leading `twist' distribution functions are obtained within the framework of a diquark spectator model using a non-local operator representation.
Distribution and fragmentation functions in a spectator model
R. Jakob, P. J. Mulders, J. Rodrigues
Quark distribution and spectator functions are estimated in a diquark spectator model. The representation of the functions in terms of non-local operators together with the rather…
Quark Distribution Functions in a Diquark Spectator Model
P. J. Mulders, J. Rodrigues
The representation of quark distribution functions in terms of nonlocal operators is combined with a simple diquark spectator model. This allows us to estimate these functions for…
Quark transverse momentum in hard scattering processes
R. Jakob, A. Kotzinian, P. J. Mulders +1
The role of transverse momentum of quarks in semi-inclusive leptoproduction will be discussed. It involves generalized distribution and fragmentation functions which depend on both…
Modelling distribution functions and fragmentation functions
J. Rodrigues, A. Henneman, P. J. Mulders
We present examples for the calculation of the distribution and fragmentation functions using the representation in terms of non-local matrix elements of quark field operators. As…
