RESULTS FROM DASP ON E+ E- ANNIHILATION BETWEEN 3.1-GEV AND 5.2-GEV

The DASP collaboration Brandelik, R. ; Braunschweig, W. ; Martyn, H.U. ; et al.

This paper summarizes the measurements one+e− annihilation performed by the DASP Collaboration in the energy range between 3.1 and 5.2 GeV. The following topics are covered: total cross section, production and two body decays of the narrow resonances, radiative decays of theJ/ψ and ψ′ resonances and evidence for theX(2.82), ψ′ cascade decays, inclusive η production and evidence for theF meson, semileptonic decays of charmed mesons and properties of the heavy lepton.

Production of Charged Kaons by e+ e- Collisions Between s**(1/2) = 3.6-GeV and 5-GeV

The DASP collaboration Brandelik, R. ; Braunschweig, W. ; Martyn, H.-U. ; et al.
Phys.Lett.B 67 (1977) 363-366, 1977.
Inspire Record 118821 DOI 10.17182/hepdata.27582

The total cross section for K ± production in e + e − collisions was measured for cms energies between 3.6 and 5 GeV and was found to increase by a factor of 2–3 from 3.6 to 4.1 GeV.
