Mesons decaying into π 0 or η and one charged meson were studied using a liquid-argon calorimeter in a non-magnetic double-arm spectrometer. Cross sections and energy dependences are presented. The ϱ ± production mechanisms are discussed in detail: ω and π exchange contribute the largest fractions, but also A 2 exchange is present. ϱ ± production by ω exchange is shown to follow the energy behaviour predicted by the Regge trajectory α ω ( t ) = 0.4 − | t |.

Study of pi- p ---> pi0 n and pi- p ---> eta n reactions in nuclei at 7.82 gev/c

Inspire Record 68531 DOI 10.17182/hepdata.33256

π − p → π 0 n and π − p → η n differential cross sections have been measured in nine nuclei ranging from hydrogen to lead at a 7.82 GeV/ c beam momentum and in a range of t going from 0 to −2 (GeV/ c ) 2 . The results can be understood in the framework of the Glauber theory which allows in addition a determination of the π 0 and η total cross sections on nucleons.

Measurement of the Differential Cross-Section and the Spin-Correlation Parameters P,A, and R in the Backward Peak of pi- p --> K0 Lambda at 5-GeV/c

Nucl.Phys.B 99 (1975) 30-52, 1975.
Inspire Record 98667 DOI 10.17182/hepdata.31861

We present measurements for the baryon-exchange reaction π − p→ Λ K 0 at 5 GeV/ c over the range − u <2(GeV/ c ) 2 . The differential cross section is obtained from events produced on a liquid hydrogen target. These data are combined with events produced on a butanol polarized target and the parameters P , A , and R are then determined from an analysis of the decay angular distribution of the forward-going Λ. From our data it is possible to determine the magnitudes and the relative phase of the two invariant amplitudes A ′ and B . The consequences for the ratio B / A ′ are discussed in detail.

A Study of the Final States anti-K0 n, Lambda pi0 and anti-K0 Delta0 in K- p Interactions at 5-GeV/c and 8-GeV/c

Inspire Record 110114 DOI 10.17182/hepdata.35539

We present results on three reactions involving neutral final states which were studied in a magnet spark chamber system. These results are: (a) differential cross section with high statistics for K − p → K 0 n at 5 GeV /c (24 000 events) and at 8 GeV/ c (11 000 events) for t′ <2.0 (GeV/ c ) 2 ; (b) differential cross section and polarization for K − p → Λπ 0 (backward peak) at 5 GeV/ c for u ′ < 1.4 GeV/ c ) 2 ; and (c) differential cross section for K − p → K 0 Δ 0 (1232) at 5 GeV /c for t′ < 1.2 ( GeV /c) 2 . We compare our results with existing data and draw some phenomenological conclusions.
