Charged Current Events with Neutral Strange Particles in High Energy Antineutrino Interactions

The results of a study of strange particle production in charged current $\bar{\nu}_{\mu} N$ interactions in the Fermilab 15 ft bubble chamber filled with a heavy $Ne-H_2$ mixture are presented. Production rates and average multiplicities of $K^0$'s and Λ's as functions of W 2 and Q 2 are given. The experimental data agree well with the quark-parton model predictions if a yield of 0.06 ± 0.02 of $K^0$'s and Λ's from charm production is included. Upper limits for D-meson production are given and the shape of the charmed quark fragmentation function is discussed. Inclusive production of the K ∗ (890) and Σ(1385) resonances is measured and it is shown that only about 5% of the K 0 mesons and Λ hyperons results from resonance decays. Relative production rates of neutral strange particles on proton and neutron targets are studied.

Measurement of the SU(3) Symmetry Violation in the Quark Jet

The Fermilab-Serpukhov-Moscow-Michigan collaboration Ammosov, V.V. ; Amrakhov, A.H. ; Denisov, A.G. ; et al.

We have used the ratio between the production rates of $K^0$'s and $π^−$'s in antineutrino-nucleon interactions in the Fermilab 15 ft bubble chamber to measure the size of the SU (3) symmetry violation in the production of quark-antiquark pairs to be 0.27 ± 0.04. This value is significantly larger than the value obtained from a recent ep experiment. There is no apparent dependence of the $K^0$/$π^−$ ratio with $W^2 , Q ^2 , x_b$ or $p_T^2$ .

Measurement of the Polarization Parameter $P$ in $\pi^- P$ Elastic Scattering in the Energy Range 450-{MeV} - 600-{MeV}

Sov.J.Nucl.Phys. 31 (1980) 92, 1981.
Inspire Record 141918 DOI 10.17182/hepdata.37948

This paper presents the results of an experiment in which the polarization parameter P in π − p elastic scattering has been measured at energies of 450, 490, 530, 560 and 600 MeV. The experiment was performed on a pion channel of the LNPI synchrocyclotron using a polarized proton target and wire spark chambers with magnetostrictive read-out. The results have substantially higher precision in comparison with other experiments in this energy range.
