Measurement of Dimuon Production at the {ISR}

Antreasyan, D. ; Atwood, W. ; Battiston, R. ; et al.

Phys.Rev.Lett. 45 (1980) 863, 1980.

Inspire Record 153857 DOI 10.17182/hepdata.20656

Prompt dimuon production has been measured. Events with mass up to 25 GeV/c2 are observed, as well as the J and ϒ resonances. Cross sections are given for J and ϒ production. For the continuum, the scaling function F(τ) is measured at very small values of τ=ms covering the range 0.05<τ<0.20.

Inclusive Production of $\rho^0$ and $\phi$ in $K^+ p$ Interactions at 32-{GeV}/c

The Soviet-CERN collaboration Vorobjev, A.P. ; Gerdyukov, L.N. ; Knyazev, V.V. ; et al.

Nucl.Phys.B 176 (1980) 303, 1980.

Inspire Record 153559 DOI 10.17182/hepdata.48999

Inclusive ϱ 0 and φ production is investigated in K + p interactions at 32 GeV/ c . Total and semi-inclusive ϱ 0 and φ cross sections, longitudinal and transverse momentum distributions, including 〈 P T versus x dependence are presented. No evidence for a sea-gull effect is observed. Comparison with quark models strongly suggests the possibility that a large fraction of the ϱ 0 and vector mesons are produced as fragmentation products of the incident particles. Study of uncorrelated π + π − pairs in the ϱ 0 mass range provides possible indirect evidence for the existence of diquarks in the proton.

INVESTIGATION ON THE REACTION t p ---> p d n AT 2.5-GeV/c TRITON MOMENTUM

Chuvilo, I.V. ; Ergakov, V.A. ; Grechko, V.E. ; et al.

Phys.Lett.B 91 (1980) 349-352, 1980.

Inspire Record 154345 DOI 10.17182/hepdata.40230

The reaction of tp → pdn in 4π geometry was investigated by exposition of an 80 cm liquid hydrogen bubble chamber to a t-nucleus beam of 2.5 GeV/ c momentum. The main characteristics of the reaction are described reasonably well by the pole approximation in the absolute normalization and without free parameters.
