Interference Fragmentation Functions in Deep Inelastic Scattering
A. Bianconi, S. Boffi, R. Jakob +1
We give a general overview of the role and interpretation of fragmentation functions in hard processes. Transverse momentum dependence gives rise to time-reversal odd fragmentation…
Comment on the paper: ``The perturbative proton form factor reexamined'' by Kundu et al
J. Bolz, R. Jakob, P. Kroll +1
We point out some serious problems in the investigation of Kundu et al. which claims agreement with the existing data of the proton form factor, calculated without taking into acco…
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…
Time reversal odd fragmentation functions
R. Jakob, P. J. Mulders
The combination of transverse momentum and polarization effects in hard scattering processes, e.g polarized deep-inelastic leptoproduction, results in a rich variety of information…
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…
