A study of Zweig's rule using phi mesons in a broad band neutral beam
… rule using phi mesons in a high energy photon beam has been performed. Measurement of the ratio sigma (gamma A -> phi pi pi A) / sigma (gamma A -> omega pi pi A) = 0.10 ± 0.02 is taken as evidence that there is not as strong suppression as could be expected. Other ratios show strange particle …

Dimuon production by high energy neutrons
In the broad band neutral beam at Fermi National Accelerator Laboratory, the dimuon production by high energy neutrons has been measured for incident neutron energies of approximately 250 and 320 GeV. The mass spectra show clear peaks in the rho-omega mass region and at the J /psi mass. Cross …

Search for semileptonic decays of photoproduced charmed mesons
In the broad band neutral beam at Fermi1ab, a search for photoproduction of charmed D mesons has been done using photons of 100 to 300 GeV. The reaction considered was [equation] s No statistically significant evidence for D production is observed based on the Ksnpi± mass spectrum. The sensitivity …

Exclusive diffractive dissociation of KL mesons at high energies
"Using the hadronic component of the Fennilab broad band neutral beam, we have observed diffractive dissociation of KL mesons with a carbon target into the exclusive final states Ks pi+pi-, K*(890)+-pi+, Ks Ksw and Kstheta , but not Ks ""t"" The diffractive production cross section for these states …

Exclusive Diffractive Dissociation of K(l) Mesons at High Energies
Using the hadronic component of the Fermilab broad band neutral beam, we have observed diffractive dissociation of K(,L) mesons with a carbon target into the exclusive final states Ks (pi)('+)(pi)('-), K*(890)('(+OR-)) (pi)('(-OR+)), Ks (rho)('0), Ks (omega)('0), and Ks (phi), but not Ks (psi). The …

Production of K+K - and ppbar pairs in high energy photoproduction
Using the Fermilab broad-band neutral beam and a multi-particle spectrometer, we have investigated the channels: photon + d ==> K+K- over ppbar (n, p, d, or X) ppbar In K+K-production, we make precise measurements of the elastic phi photoproduction cross section between 35 GeV and 85 GeV. Between …

High energy photoproduction of rho and phi vector mesons
… phi vector mesons from hydrogen in the Fermilab broad band neutral beam. Forward going two particle final states were detected in a multiparticle spectrometer consistIng of two analyzing magnets, a multiwire-proportional-chamber tracking system and a particle identification system. Recoil protons …
