Results are presented on the reaction K − p → K̄ o n for momenta above 20 GeV/ c . Events were identified by precise measurement of the opening angle in the decay K o → π + π − without using a magnetic field. The cross-section is described by a power energy dependence.

The total hadronic photoabsorption cross sections of a number of nuclei (C, Al, Cu, Nb, Sn, Ta, Pb) have been studied in detail using a tagged photon beam over the energy range 1.7-4 GeV. The results are described, and compared with models of photoabsorption.

Pi0 and pi+ Production with Polarized Photons in the Energy Range 1-GeV - 2-GeV

Phys.Lett.B 48 (1974) 463-466, 1974.
Inspire Record 90760 DOI 10.17182/hepdata.43798

The asymmetry of π o and π + photoproduction from hydrogen has been measured. The π o -mesons were detected at 130° cms with E γ ranged from 0.9 to 1.65 GeV, and the π + -mesons at 40° cms with E γ ranged from 0.9 to 1.2 GeV. The results agree with model predictions of single pion photoproduction in the resonance region using fixed- t dispersion relations.

Observation of a Spin 4 Neutral Meson with 2-GeV Mass Decaying in pi0 pi0

The invariant mass spectrum of neutral meson states from π − p interactions at 40 GeV/ c incident momentum has been investigated in a high statistics experiment performed at the 70 GeV IHEP accelerator. To detect the high energy photons coming from the produced neutral states, a hodoscope spectrometer with a computer on-line was used. A clear structure on the mass spectrum of dipions produced in the reaction π − p→π°π°n is observed at 2 GeV. The decay angular distributions show in this mass region the variation with mass typical of a state with a spin J = 4. The mass of the observed meson is found to be M = (2020±30)MeV and the estimate of the full width is (180±60) MeV.

In a streamer-chamber experiment at the Stanford Linear Accelerator Center, we observed hadron production in inelastic collisions of 14-GeV positive muons in a liquid hydrogen target. We report on the experiment, the analysis, and the resulting cross sections for hadronic prongs as well as the charged-hadron multiplicity distributions.

Inclusive Single Particle Production at 90-Degrees in the Center-Of-Mass System for Nuclear Targets and 28.5-GeV/c Incident Protons

Inspire Record 115394 DOI 10.17182/hepdata.21074

The invariant cross section for the inclusive production of π+, π−, K+, K−, p, and p¯ is presented for proton-nucleon interactions at plab=28.5 GeV/c. Beryllium, titanium, and tungsten targets were used and the yields were extrapolated to A=1 using the power law σ∼Aα. The exponent α increases with pT, except for protons. The pT dependence of the cross sections is compared with a simple fireball model.
