Description
The inclusive production of the meson resonances $\rho^{0}(770)$, $f_0(980)$,
$f_2(1270)$, $K^{*+}(892)$ in neutrino-nucleon interactions has been
studied with the NOMAD detector. The detector was exposed to the wide band neutrino beam
generated by 450-GeV protons at CERN SPS. For the first time the $f_{0}(980)$
meson is observed in neutrino interactions. The presence of $f_{2}(1270)$ in the neutrino interactions is reliably established. The average multiplicity of these three resonances
is measured as a function of several kinematic variables.
The experimental results are compared to the multiplicities obtained from a
simulation based on the Lund model.
Matrix element of spin density matrix
for $K^{*+}(892)$ meson have been measured.
