In a high statistics (180 events/μb) bubble chamber study of the reaction fx K − p → K 0 π − p at 8.25 GeV c , we observe a K 0 π − state at 2088±20 MeV with a width 170 +100 −50 MeV, produced with a cross section of 3.6±1.2 μ b. In addition we observe this state in the channels K ∗ (890)ππ , ϱ K π , ω K π with a combined cross section of 7.1±2.6 μ b, and possibly K ∗ (890)πππ .

Measurement of R in $e^+ e^-$ Annihilation for $\sqrt{s}$ Between 7.4-{GeV} and 9.4-{GeV}

The LENA collaboration Niczyporuk, B. ; Jakubowski, Z. ; Nowak, G. ; et al.
Z.Phys.C 15 (1982) 299, 1982.
Inspire Record 179431 DOI 10.17182/hepdata.16412

The rationR=σ(e+e−→hadrons)/σ(e+e−→ µ+ µ−) was measured with the LENA detector at DORIS in a scan between 7.40 and 7.48 GeV and between 8.67 and 9.43 GeV center of mass energies. Corrected for QED radiative effects,R is found to be constant with an average value ofR=3.37 ±0.06stat±0.23syst. No narrow resonances withΓee(Γhad/Γtot)⊗0.30 keV (95% C.L.) and no steps have been observed. Based on this value ofR, revised values for υ(1S) resonance parameters are presented.

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

Inspire Record 181635 DOI 10.17182/hepdata.10881

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.

Observation of a Parity Violation in Cesium

Bouchiat, M.A. ; Guena, J. ; Hunter, L. ; et al.
Phys.Lett.B 117 (1982) 358, 1982.
Inspire Record 180105 DOI 10.17182/hepdata.30837

We have measured a parity violation in the 6S–7S transition of Cs in an electric field. Our result is Im E 1 pv β = -1.34 ± 0.22 ( rms statistical deviation ) ± ∼0.11 ( systematic uncertainty ) mV cm; E 1 pv is the parity violating electric dipole amplitude, ß is the vector polarizability. This result is consistent with the Weinberg-Salam prediction.

Measurement of the Proton - Anti-proton Elastic and Total Cross-section at a Center-of-mass Energy of 540-{GeV}

First results on the measurement of the elastic and total cross section at the CERN pp̄ Collider are presented. Combining the measurement of elastic scattering at low momentum transfer with the rate of inelastic interactions, a value of the total cross section of 66 mb with a 10% statistical error was obtained.
