Mapping the proton unintegrated gluon distribution in dijets correlations in real and virtual photoproduction at HERA
A. Szczurek, N. N. Nikolaev, W. Schäfer +1
We discuss how the dijet azimuthal correlations in DIS and real photoproduction at HERA probe the differential (unintegrated) gluon distribution in the proton. We find a strong dep…
asymmetry and semi-inclusive production of pions in DIS
A. Szczurek, V. Uleshchenko, J. Speth
We investigate unambiguities in the extraction of the asymmetry from semi-inclusive production of pions in DIS. The role of several effects beyond the quark-parto…
The reactions p + n --> d + omega and p + n --> d + phi near threshold
K. Nakayama, J. Haidenbauer, J. Speth
The reactions p+n-->d+omega and p+n-->d+phi are studied within a relativistic meson-exchange model of hadronic interactions. Predictions for the total cross sections and for the an…
Near threshold Lambda and Sigma production in pp collisions
A. M. Gasparian, J. Haidenbauer, C. Hanhart +2
A model calculation for the reactions and near their thresholds is presented. It is argued that the experimentally observed strong suppression of pr…
On the Migdal-Watson approach to FSI effects in meson production in NN collisions
V. Baru, A. M. Gasparian, J. Haidenbauer +2
The influence of the nucleon-nucleon final state interaction (FSI) on properties of the meson production amplitude near threshold is discussed. For the nucleon-nucleon interaction…
Polarization phenomena in the reaction NN to NNpi near threshold
C. Hanhart, J. Haidenbauer, O. Krehl +1
First calculations for spin-dependent observables of the reactions , and near threshold are presented, employing the Jülich model for pio…
