Search for New S Anti-s States in the $K^-$ Induced $K^+ K^-$ System

Results from the first PWA of the K + K − system produced by incident K − , are presented in the mass range from the threshold to 1.70 GeV. In the P and D waves only the φ and f′ mesons are observed and their production mechanism studied. A broad S wave peaking at 1.4 GeV is observed but the lack of information about its phase makes the search for new 0 ++ mesons inconclusive.

CHARM PHOTOPRODUCTION CROSS-SECTION AT 20-GeV

Inspire Record 189662 DOI 10.17182/hepdata.20508

Forty-seven charm events have been observed in an exposure of the SLAC Hybrid Facility bubble chamber to a 20-GeV backward-scattered laser beam. Thirty-seven events survive all the necessary cuts imposed. Based on this number the total charm cross section is calculated to be 63−28+33 nb.

Measurement of the Rate of Increase of Neutrino Cross-Sections with Energy

Blair, R. ; Barish, B.C. ; Chu, Y.K. ; et al.
Phys.Rev.Lett. 51 (1983) 343-346, 1983.
Inspire Record 194360 DOI 10.17182/hepdata.20507

The energy dependence of the cross section for neutrino- and antineutrino-nucleon charged-current interactions has been determined from data taken in Fermilab's dichromatic neutrino beam. σνE=(0.669±0.003±0.024)×10−38 cm2/GeV and σν¯E=(0.340±0.003±0.02)×10−38 cm2/GeV are found. These results are higher than some previous measurements.

Inspire Record 188803 DOI 10.17182/hepdata.20525

The branching fraction for the decay of the ϒ(1S) into τ paris has been measured to be (3.4±0.4±0.4)%. This result agrees with the previously measured branching ratio of the decay into muon pairs.

A Measurement of the Leptonic Branching Ratios of the $\Upsilon$ (1s), $\Upsilon$ (2s), and $\Upsilon$ (3s)

The CLEO collaboration Andrews, D. ; Avery, P. ; Berkelman, Karl ; et al.
Phys.Rev.Lett. 50 (1983) 807, 1983.
Inspire Record 188805 DOI 10.17182/hepdata.20536

Using the CLEO detector at the Cornell Electron Storage Ring, the authors have measured the leptonic branching fractions, Bμμ, of the ϒ(1S), ϒ(2S), and ϒ(3S) to be 2.7±0.3±0.3%, 1.9±1.3±0.5%, and 3.3±1.3±0.7%, respectively. Combining these values of Bμμ with previous measurements of the leptonic widths of these resonances, the authors find the total widths of the ϒ(1S), ϒ(2S), and ϒ(3S) to be 48±4±4, 27±17±6, and 13±4±3 keV.
