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 $100 < Q^2 < 20 000 \GeV^{2}$. 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.

Liquid-gas coexistence in Pb-208 emulsion interactions at 160-A-GeV

The charge distribution of multifragments of the 208 Pb beam at 160A GeV in nuclear emulsion has been fitted with a power-law. The moments of the resulting nuclear charged fragment distribution dis provide strong evidence that nuclear matter possesses critical point observables. The values of the critical exponents (γ, β and τ) extracted from the 208 Pb beam are compared with the values for the 197 Au beams at 10.6A GeV and 1A GeV. These values are very close to those for a liquid-gas system.

Properties of Multiplicity Distributions in $\nu A$ and $\bar{\nu}A$ Interactions at $E_{\nu/\bar{\nu}}\le 30$-{GeV}

Inspire Record 197246 DOI 10.17182/hepdata.16364

We present data on the multiplicity structure of inclusive charged hadron production in charged current neutrino and antineutrino freon interactions in the energy range 3–30 GeV resulting from an experiment with the bubble chamber SKAT. Average multiplicities, dispersions and correlation coefficients are investigated. Furthermore, KNO-scaling is studied and average net charges are calculated in different kinematical regions. Our data are compared with results from\(\begin{array}{*{20}c}{( - )}\\v\\ \end{array} \)-interactions on an isoscalar target of “free” nucleons to study the influence of nuclear effects.

Energy and Quantum Number Flow in $K^+ p$ and $\pi^+ p$ Interactions at 32-{GeV}/$c$ and 70-{GeV}/$c$

Energy, charge and strangeness flow inK+p interactions at 32 and 70 GeV/c, and π+p interactions at 32 GeV/c are studied in terms of the angular variable λ=|x|/pT. The data ondQ/dλ anddE/dλ show only a weak indication of scale breaking between 32 and 70 GeV/c. For inclusive “non-diffractive”, inclusive “diffractive” and exclusive “non-diffractive” jets, the fraction of charge in any angular region ΔΩ away from the central region is found to be proportional to the energy fraction in the same interval. The data ondQ/dE versus λ are compatible with some versions of dual-sheet models and agree also with the LUND Monte-Carlo model. The data are also compared with\(v(\bar v)p\) interactions in BEBC. In exclusive channels the average ratiodQ/dS=0.78±0.04 is consistent, in the framework of fragmentation models, with a larger probability for the fragmentation of the\(\bar s\)-valence quark than theu-valence quark in theK+-meson.
