چکیده
We investigate the effect of the electric formfactor on dilepton production off pp-collisions. In the model we use, the formfactor is separated in a pion-cloud contribution and a Vector Meson Dominance part. We find that the dilepton spectrum is hardly affected by the pion-cloud part, but significantly by the VMD contribution. We point out that data with sufficient resolution would provide a crucial test of the validity of VMD for the nucleon formfactor in the timelike region.

Phi meson production in heavy-ion collisions at subthreshold energies is studied in the relativistic transport model. We include contributions from the baryon-baryon, pion-baryon, and kaon-antikaon interactions and find that the reaction πN → φN is most important for phi meson production. The implication of our results is discussed with respect to the preliminary experimental data from the FOPI...

Dilepton production in proton-and nucleus-induced reactions is studied in relativistic transport model using initial conditions determined by the string dynamics from RQMD. It is found that both the CERES and HELIOS-3 data for dilepton spectra in proton-nucleus reactions can be well described by the 'conventional' mechanism of Dalitz decay and direct vector meson decay. However, to provide a qu...

Starting from a realistic one–boson–exchange–model fitted to the amplitudes of elastic nucleon–nucleon scattering and the process N N → N ∆ we perform a fully relativistic and gauge invariant calculation for the dilepton production in nucleon–nucleon collisions, including the important effect of propagating the ∆–resonance. We compare the results of our calculations with the latest experimental...

Neutral pion (π 0) production is calculated in a leading order (LO) perturbative QCD-based model in pp and dAu collisions at √ s = 200 AGeV at midrapidity. The model includes the transverse component of the initial parton distribution. We compare our results for pp collision to experimental data at RHIC energy. We repeat our calculation for the dAu collision and investigate the interplay betwee...

Dilepton production following radiative capture of a proton on a nuclear target is studied in the Impulse Approximation. The cross section is decomposed in terms of four time-like nuclear structure functions through a longitudinal-transverse separation of the nuclear current. Using a simple PWIA model, cross sections and conversion factors are calculated for capture at proton energies of 100-20...
