From soft to hard regime in elastic pion-pion scattering above resonances
A. Szczurek, N. N. Nikolaev, J. Speth
We discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component of pQCD hard two-gluon (2G) exchange contribution to hard elastic scattering at moderate…
Eta-N Final State Interaction in incoherent Photoproduction of Eta-mesons from the Deuteron near Threshold
A. Sibirtsev, S. Schneider, Ch. Elster +3
An analysis of incoherent photoproduction of mesons off the deuteron for photon energies from threshold to 800 MeV is presented. The dominant contribution, the N-N amplit…
A meson exchange model for the YN interaction
J. Haidenbauer, W. Melnitchouk, J. Speth
We present a new model for the hyperon-nucleon (Lambda N, Sigma N) interaction, derived within the meson exchange framework. The model incorporates the standard one boson exchange…
Phenomenological analysis of K+ meson production in proton-nucleus collisions
M. Buescher, B. L. Ioffe, V. Koptev +5
Total and differential cross sections from literature, on the production of K+ mesons in pA interactions at projectile energies between T=0.8 and 2.9 GeV, covering the transition a…
The reaction revisited: the scattering length
C. Hanhart, A. Sibirtsev, J. Speth
We reinvestigate the experimental data on --meson production in pion-nucleon collisions based on both an analytical approach and a Monte Carlo simulation. Our analysis allows us…
Towards mapping the proton unintegrated gluon distribution in dijets correlations in real and virtual photoproduction at HERA
A. Szczurek
It is discussed how the dijet azimuthal correlations in DIS and real photoproduction at HERA probe the unintegrated gluon distribution in the proton. The correlation function shows…
Incoherent Photoproduction of -mesons from the Deuteron near Threshold
A. Sibirtsev, Ch. Elster, J. Haidenbauer +1
Incoherent photoproduction of the -meson on the deuteron is studied for photon energies from threshold to 800 MeV. The dominant contribution, the N-N amplitude, is describ…
