Approximately 700 events of the reaction K − d → K − π − pp s produced by 5.5 GeV/ c kaons were used to measure the cross section for Kπ elastic scattering in the T = 3 2 state by a Chew-Low extrapolation. The cross section does not exceed 2.1 mb and has no structure for Kπ masses from threshold up to 2.0 GeV.

Production of the k- pi+ pi- n final state in k- d interactions at 5.5 gev/c

Inspire Record 75079 DOI 10.17182/hepdata.32866

The reaction K − d → K − π + π − n p s was studied in a bubble chamber experiment. The cross section was measured to be 1.3 ± 0.2 mb. The final state is dominated by K ∗0 (890) , K ∗0 (1420) and Δ − (1236) production. Partial cross sections, differential cross sections and decay angular distributions of the K ∗0 (890) δ − (1236) final state were found to give good agreement with the predictions of Białas and Zalewski obtained from the quark model. The final state K − π + Δ − (1236) is analyzed by use of the Van Hove plot.

K- d interactions at 5.5 gev/c - sigma-+ pi+- pi-(pi0), sigma- k+, k- and k- pi- p final states in which a hyperon is produced

The results presented in this paper are obtained from an analysis of bubble-chamber pictures of K−d interactions at an incident K− momentum of 5.5 GeV/c. Generally, the quasitwo-body final states are produced peripherally, with a small backward peak occurring in some of the final states. The final states Σ−ω, Σ−ρ0, and Σ−φ appear to be produced primarily by vector-meson exchange. In the final state Λ(1520)π− the decay distributions of the Λ(1520) hyperon are found to be consistent with a vector-exchagne production process with M2 coupling at the nucleon vertex. The predictions of the independent-quark model and of other symmetry schemes, namely that the forward cross sections for Σ−ρ0, Σ−ω, Σ−φ production be in the ratios 1: 1: 2, are not inconsistent with our experimental values.

A STUDY OF DOUBLE TAGGED TWO PHOTON REACTIONS AT SPEAR

Inspire Record 159793 DOI 10.17182/hepdata.27144

We have identified 262 doubly tagged two-photon events. A subset of the data shows an enhancement of 21 events in the inclusive two-photon mass squared distribution between 0.8 and 2.2 GeV 2 . If these events result from spin 2 resonance production then Γ γγ = 9.5 ± 3.9 ± 2.4 keV (statistical and systematic). From another subset of 58 events in which the final state could be classified we determine the two-photon hadron to muon cross section ratio R γγ = 1.1 ± 0.3 ± 0.3.

BACKWARD PRODUCTION OF THE B (1235) MESON IN 11.46-GEV/C PI+ P INTERACTIONS

Wong, M.K. ; Key, A.W. ; Schwarzschild, B.M. ; et al.
Phys.Rev.Lett. 46 (1981) 974, 1981.
Inspire Record 169864 DOI 10.17182/hepdata.20643

Evidence for the backward production of the B(1235) meson in the final state π+p→pfπ+ω at 11.46 GeV/c with σ(|u′|<1.5 GeV2)=1.28±0.26 μb is presented. When nucleon exchange is assumed to dominate, estimates for the SU(3) mixing parameter FD as well as the B coupling to the nucleon-antinucleon are given. Some indication of a narrow enhancement at M(π+ω)≃1.03 GeV/c2 is seen, but confirmation of this as a resonant state is not yet possible.

PARTIAL WAVE ANALYSIS OF THE K+ PI+ K- SYSTEM SEEN IN THE REACTION PI+ P ---> K+ PI+ K- P AT 11.46-GeV/c

Inspire Record 194990 DOI 10.17182/hepdata.23837

We present results of a hybrid-bubble-chamber experiment examining the reaction π+p→π+pK+K− at an incident momentum of 11.46 GeV/c. The total cross section for this channel is determined to be 87.2±6.4 μb. A partial-wave analysis of the K+π+K− system reveals no unambiguous evidence of resonant activity, although mass enhancements are noted in the JP=0− κ¯K+ (S wave), JP=2− fπ (S wave), and JP=2−, K¯*0(892)K+ (P wave). This is the first published report of the relative phases of the waves seen in this reaction. We comment on the influence this channel may have on A1 and A3 production.
