Inclusive Strange Resonance Production in $p p$, $\pi^+ p$ and $K^+ p$ Interactions at 147 GeV/c

Brick, D. ; Rudnicka, H. ; Shapiro, A.M. ; et al.

Phys.Rev.D 25 (1982) 2248-2258, 1982.

Inspire Record 176545 DOI 10.17182/hepdata.23976

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.

Phys.Rev.D 26 (1982) 1554-1571, 1982.

Inspire Record 182973 DOI 10.17182/hepdata.23971

Results from a high-statistics experiment involving an exposure of the SLAC 82-in. hydrogen bubble chamber to a beam of 8-GeV/c π− yielding a final state of π−π+π−p are presented. Copious production of ρ, Δ++, and f is found. Considerable quasi-two-body production in which one particle decays to one of the above resonances is also observed. Some double-resonance production involving baryon and meson resonances is also seen. The production properties of ρ, Δ++, and f mesons are well described by a double-Regge model.

REACTION K+ P ---> K N PI PI AT 4.27-GeV/c INCIDENT MOMENTUM

Gelfand, N.M. ; Lasinski, B. ; Leary, P. ; et al.

Phys.Rev.D 26 (1982) 2973-2978, 1982.

Inspire Record 184512 DOI 10.17182/hepdata.23895

The cross sections for K+p interactions at a center-of-mass energy of 3 GeV (4.3 GeV/c incident momentum) have been determined for the K+pπ+π−, K0pπ+π0, and K0π+π+n final states. The shape of the differential cross section dσdt′ for the quasi-two-body final state K*0(890)+Δ++(1236) is not a single exponential. Characteristics of the low-mass Kππ and pππ enhancements are discussed.

From a study of 8-GeV/c π−p interactions, the various two-pion and four-pion decay channels available to the g− meson have been investigated. Our results indicate that the dominant 4π decay modes involve intermediate ρ and ω production without significant A2 formation.

ELASTIC SCATTERING AND PARTICLE PRODUCTION IN TWO PRONG PI- P INTERACTIONS AT 8-GEV/C

Phys.Rev.D 26 (1982) 1572-1587, 1982.

Inspire Record 182974 DOI 10.17182/hepdata.23945

Results of a high-statistics study of elastic scattering and meson resonances produced by π−p interactions at 8 GeV/c are presented. Large statistics and small systematic errors permit examination of the complete kinematic region. Total differential cross sections are given for ρ0,−, f0, g0,−, Δ±, Δ0, and N* resonances. Spin-density matrix elements and Legendre-polynomial moments are given for ρ, f, and Δ resonances. The results for ρ0 and f0 resonances are compared with the predictions of a Regge-pole-exchange model. Properties of the above resonances are compared and discussed. In particular, we present evidence that the ρ0 and f0 production mechanisms are similar. The similarity of the g0 t distribution to that of the ρ0 and f0 suggests a common production mechanism for all three resonances.

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

Van Apeldoorn, G.W. ; Harting, D. ; Holthuizen, D.J. ; et al.

Z.Phys.C 12 (1982) 95-98, 1982.

Inspire Record 179937 DOI 10.17182/hepdata.16432

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.

DECAY OF B MESONS INTO CHARGED AND NEUTRAL KAONS

Phys.Rev.Lett. 48 (1982) 1070-1074, 1982.

Inspire Record 180612 DOI 10.17182/hepdata.27749

Data on inclusive kaon production in e+e− annihilations at energies in the vicinity of the ϒ(4S) resonance are presented. A clear excess of kaons is observed on the ϒ(4S) compared to the continuum. Under the assumption that the ϒ(4S) decays into BB¯, a total of 3.38±0.34±0.68 kaons per ϒ(4S) decay is found. In the context of the standard B-decay model this leads to a value for (b→c)(b→all) of 1.09±0.33±0.13.
