The study of neutral strange particle production in antineutrino-induced neutral current interactions is presented. The total multiplicity of neutral strange particles and the K 0 multiplicity in the current fragmentation region ( z >0.3) are used to estimate in two ways the coupling strength of the weak neutral current to the strange quark.

Inclusive Charged Hadron Spectra in $\nu A$ and $\bar{\nu} A$ Interactions at $E_{\nu/\bar{\nu}} < 30$-{GeV}

We present inclusive spectra of charged hadrons produced in$\begin{array}{*{20}c}{( - )}\\v\\ \end{array}$-Freon interactions at average beam energies of about 6 GeV. The experiment was done using the bubble chamber SKAT at the 70 GeV Serpukhov accelerator. In the hadronic energy range,W<5 GeV, dominantly isotropic events are found. The transverse momentum of the produced particles shows no strongW2-dependence. Feynman-scaling may be reached forW2≳10 GeV2, where also theż-spectra are described by the predictions of the parton model. All experimental data are reproduced rather well also by a Monte Carlo model based on ordinary phase space.

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

Z.Phys.C 21 (1984) 189, 1984.

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.
