Strange quark suppression in 225 GEV/C pi-minus beryllium interactions
The Chicago Cyclotron Magnet Spectrometer at Fermi1ab was used to study the production of W (783) and rp (1020) mesons in 225 GeV/c pi--Be interactions via their decays into pi+pi- ratio, the strange quark suppression factor.A was determined to be 0.31 ± 0.05, in good agreement with a world average …

Strange Quark Suppression in 225 Gev/c Negative Pion Beryllium Interactions
The Chicago Cyclotron Magnet Spectrometer at Fermilab was used to study the production of (omega)(783) and (phi)(1020) mesons in 225 GeV/c (pi)('-) Be interactions via their decays into (mu)('+)(mu)('-). Based on the observed (phi)/(omega) production ratio, the strange quark suppression factor …

Production of Neutral D (1863) Mesons in 217 Gev/c Negative Pion Proton Interactions
… FNAL experiment E369. The Chicago Cyclotron Magnet Spectrometer Facility was used to perform a search for the hadronic production of charmed D mesons. A 217 Gev (pi)('-) beam was incident on a liquid hydrogen target. The trigger required a slow recoil proton in coincidence with a muon. A …

Comparison of pion- and proton- production of charmonium
… was carried out with the Chicago Cyclotron Magnet Spectrometer at Fermilab. The fraction of J/""s resulting from X decay is measured to be 0.33±O.07 for incident pions and 0.47±0.2l for incident protons. The X(35l0) and X(3555) are produced in roughly equal numbers for pions, but the X(3555) …

Comparison of Pion- and Proton-Production of Charmonium
… was carried out with the Chicago Cyclotron Magnet Spectrometer at Fermilab. The fraction of J/(PSI)'s resulting from (chi) decay is measured to be 0.33 (+OR-) 0.07 for incident pions and 0.47 (+OR-) 0.21 for incident protons. The (chi)(3510) and (chi)(3555) are produced in roughly equal …

Production of charmonium states in 225 GeV/c pi-minus beryllium interactions
… FNAL experiment EG10. The Chicago cyclotron Magnet Spectrometer was used to perform a study of the hadronic production of charmonium. A 225 GeV/c negative pion beam was incident on a beryllium target. The trigger required a dimuon signature which favored opposite sign muon pairs with a large …

Production of Charmonium States in 225 Gev/c Negative Pion Beryllium Interactions
… FNAL experiment E610. The Chicago Cyclotron Magnet Spectrometer was used to perform a study of the hadronic production of charmonium. A 225 GeV/c negative pion beam was incident on a beryllium target. The trigger required a dimuon signature which favored opposite sign muon pairs with a large …

Charged-particle tracking for neutron-deuteron breakup
… proton energy is determined using a permanent magnet spectrometer, consisting of two permanent magnets placed between two wire chamber detectors. A particle tracking code uses the particle hit positions in the wire chambers to determine the proton's curvature (and hence deduce its energy) as it …

Towards a precise measurement of the cosmic-ray positron fraction
… a new detector, called Positron Electron Balloon Spectrometer (PEBS), is presented. Intended for a measurement of the cosmic-ray positron fraction on one or more flights at high altitude using a long-duration balloon, PEBS will have an unprecedentedly high acceptance of almost 0.4m^2sr. A first …
