The influence of collision centrality upon spectra of negative particles produced indC, αC and CC interactions at 4.2 GeV/c per nucleon is studied. The netcharge of secondary particles is used as a measure of collision centrality. Comparison with the nucleon-nucleon collisions and with Dubna intranuclear cascade model is presented. The main features of the momentum, rapidity and angular spectra are compatible with the independent, nucleon-nucleon collision picture. Only in thepT spectra, the observed particle excess, for low and highpT, is inconsistent with this approach. In contrast to the pions, the spectra of protons are more sensitive to the collision centrality.

Charged Particle Production in High Q2 Deep-Inelastic Scattering at HERA

The H1 collaboration Aaron, F.D. ; Aktas, A. ; Alexa, C. ; et al.

The average charged track multiplicity and the normalised distribution of the scaled momentum, $\xp$, of charged final state hadrons are measured in deep-inelastic $\ep$ scattering at high $Q^2$ in the Breit frame of reference. The analysis covers the range of photon virtuality $100 &lt; Q^2 &lt; 20 000 \GeV^{2}$. Compared with previous results presented by HERA experiments this analysis has a significantly higher statistical precision and extends the phase space to higher $Q^{2}$ and to the full range of $\xp$. The results are compared with $e^+e^-$ annihilation data and with various calculations based on perturbative QCD using different models of the hadronisation process.
