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…
