We have studied the inclusive production of K*±(890) and Y*±(1385) in pp, π+p, and K+p interactions at 147 GeV/c. The experiment used the Fermilab 30-inch hydrogen bubble chamber with the hybrid spectrometer system. Results are based on a sample of 1916 observed KS and 932 observed A. Inclusive cross sections are given for K*± and Y*± production from the three beams, and comparisons are made with experiments at other energies. Feynman-x and transverse-momentum-squared distributions are also calculated. The results suggest that the K*− is entirely produced in the central region, while the K*+ includes a component from beam fragmentation. Comparisons are made with the additive quark model.

SEARCH FOR NONSTRANGE BARYONIUM STATES IN THE BARYON EXCHANGE REACTION K- P ---> Y0 ANTI-P P AT 18.5-GeV/c

Narrow baryonium production in the baryon exchange reactions K − p → Λ p p and K − p → pK − p p at 18.5 GeV/ c is investigated in a 12 events/nb experiment performed at the CERN Ω′ spectrometer. No narrow structure is observed in the p p mass spectra. Upper limits for production of baryonium states are given as a function of p p mass.

A PARTIAL WAVE ANALYSIS OF THE K PI PI SYSTEM PRODUCED IN THE REACTION K- P ---> ANTI-K0 PI+ PI- N AT 8.25-GeV/c

A partial-wave analysis of the K 0 π + π − system from the reaction K − p → K 0 π + π − n has been carried out using data obtained at 8.25 GeV/ c in a high-statistics experiment. A strong signal appears in the 1 + SO + (K ∗ π) wave at the Q 2 mass (≈ 1.4 GeV). The 1 + S0 + (ϱK) wave behaves rather like a background and does not exhibit the characteristics of a resonance. A prominent signal also appears in the 2 + D wave (via K ∗ π and ϱK); it is interpreted as the K ∗ (1430). In the L region (1.6–2.1) GeV, there is evidence for the 3 − K ∗ (1780) while the 2 − wave also gives some contribution.

STUDY OF THE REACTIONS K+- P ---> K0(S) PI+- P AT 30-GEV/C AND 50-GEV/C: DESCRIPTION OF THE APPARATUS AND AMPLITUDE ANALYSIS OF THE K0(S) PI SYSTEM

The reactions K ± p→K s 0 π ± p are studied at 30 and 50 GeV/ c . Data for these reactions were obtained using the Geneva-Lausanne spectrometer whose main characteristics are: (i) large forward acceptance; (ii) high-resolution time-of-flight for recoil proton momentum measurement; (iii) high data-taking rate and on-line pattern recognition. The K ∗ (1 − ), K ∗ (2 + ), K ∗ (3 − ) and K ∗ (4 + ) resonance parameters and production cross sections are determined. The K π production amplitudes are calculated both as a function of the K π mass and of the momentum transfer. Isoscalar natural parity exchange (NPE) is dominant. The NPE amplitudes are decomposed into pomeron- f-, ω-exchange contributions, and their energy dependence between 10 and 50 GeV/ c is shown to be well-described by a Regge pole model based on the f-dominated pomeron hypothesis.

MEASUREMENTS OF THE MULTIPLICITIES IN THE COLLISION OF HADRONS WITH HEAVY NUCLEI AT 200-GEV/C

We report on the interactions of an incident 200 GeV / c beam composed of 33% protons, 16% kaons, and 48% pions on targets of silver and gold mounted in the Fermilab 30″ bubble chamber. Within our limited statistics, we find the total cross sections and average multiplicities to agree with previously published data. We find the KNO scaling distribution curve to be broader for heavy nuclei than for hydrogen. We present the first data for V 0 production on gold and silver. We also present, for the first time, evidence for a positive charge excess among the sample of relativistic tracks from interactions on gold and silver. We observe a trend where the positive charge excess increases with target atomic number and with increasing charged particle multiplicity. We find the charge excess to exist among the sample of particles having greater than 2 GeV / c momentum and to persist in the sample with momentum greater than 4 GeV / c .

In a high statistics bubble chamber study the reaction K − p → φφΛ is detected with a cross section of 0.7±0.2 μ b. The ratio of φφ production in K − and π − induced reactions is found to be ∼5; this is about ten times smaller than the ratio for the corresponding single φ production reactions.

The dissociation of a K− into the K−ϕ system is studied at 8.25 GeV/c. The cross-section for K−ϕp production is (27±2) μb. All the expected properties of diffraction are found (mass spectrum, mass-slope correlation, 1+S wave dominance). There is also an indication of the Kϕ decay mode of a 2− resonance in theL region.

THE REACTION ANTI-P P ---> DELTA (1236) ANTI-DELTA (1236) AT BEAM MOMENTA OF 7.23-GEV/C AND 12.0-GEV/C

The reactionp→Δ(1236)\(\bar \Delta \)(1236) is studied at 7.23 GeV/c and at 12GeV/c in terms of the OPE model of Wolf. Good agreement between the model and experimental data is found for the mass andt distributions whereas for decay angular distributions the agreement is less satisfactory. A modified model, allowing for a spin orbit coupling, gives good agreement also for the angular distribution.

The Fermilab 15-ft bubble chamber, filled with a heavy neon-hydrogen mix, was exposed to a narrow-band νμ beam. Based on the observation of 830 charged-current νμ interactions, the cross section was found consistent with a linear rise with the neutrino energy in the interval 10 GeV<~Eν≲240 GeV. The average slope was determined to be σνEν=(0.62±0.05)×10−38 cm2 GeV−1.
