Neutral Current $\nu_\mu \eta$ and $\nu_\mu \rho$ Cross-sections from High-energy Neutrino Interactions in Deuterium

Kafka, T. ; Mann, W.A. ; Sommars, S. ; et al.
Phys.Rev.Lett. 48 (1982) 910-914, 1982.
Inspire Record 180620 DOI 10.17182/hepdata.20576

In an exposure of the deuterium-filled 15 ft bubble chamber, σ(νμn→νμX)σ(νμp→νμX) is measured to be 1.01±0.14. The ratios of neutral-current to charged-current cross sections are 0.30±0.03, 0.22±0.03, and 0.49±0.06 for D2, n, and p targets, respectively, which imply values uL2=0.19±0.06 and dL2=0.13±0.04 for the neutral-current chiral couplings. Evidence for both u- and d-quark jets in neutral-current reactions is observed in distributions of energy fraction of the fastest hadron of either charge from each event.

NEW DECAY MODE OF THE CHARMED BARYON, LAMBDA(C)+ ---> SIGMA0 PI+

Kitagaki, T. ; Tanaka, S. ; Yuta, H. ; et al.
Phys.Rev.Lett. 48 (1982) 299-301, 1982.
Inspire Record 177920 DOI 10.17182/hepdata.20615

In a sample of approximately 17500 charged-current neutrino-deuterium interactions from an exposure of the Fermilab 15-ft bubble chamber to a high-energy wide-band neutrino beam, the charmed baryon Λc+ is observed in a new decay mode, Λc+→Σ0π+. The product of branching ratio and production rate is estimated to be (3.2±2.1)×10−3 for this Σ0π+ channel.

NEUTRINO FLUX AND TOTAL CHARGED CURRENT CROSS-SECTIONS IN HIGH-ENERGY NEUTRINO DEUTERIUM INTERACTIONS

Kitagaki, T. ; Tanaka, S. ; Yuta, H. ; et al.
Phys.Rev.Lett. 49 (1982) 98-101, 1982.
Inspire Record 182030 DOI 10.17182/hepdata.20571

From 12000 charged-current νμ D events obtained in an exposure of the Fermilab 15-ft bubble chamber to a high-energy wide-band neutrino beam, the absolute neutrino flux is determined using the reaction νμn→μ−p. For the total charged-current cross section, σt=kEν, k=(0.68±0.04±0.10)×10−38 cm2/GeV is obtained for Eν between 10 and 200 GeV. No clear energy dependence of the slope parameter k is observed.

A Study of Inclusive Xi-, Xi (1530) and $\omega^-$ Production in $K^- p$ Interactions at 8.25-{GeV}/$c$

The Birmingham-CERN-Glasgow-Michigan State-Paris collaboration Baubillier, M. ; Bloodworth, I.J. ; Bossen, G.J. ; et al.

Inclusive Ξ − production is studied in K − p interactions at 8.25 GeV/ c using about 8000 events. An analysis based on the triple-Regge model shows that the Λ α − Λ γ and Σ β − Σ δ exchanges explain the forward Ξ − production. Ξ(1530) properties are also studied and are found to be similar to those of Ξ − 's. Finally, a study of the production of Ω − based on 67 events shows that Ω's are also produced by hyperon exchange.
