This investigation was performed with a 24-liter propane bubble chamber [i] and is a continu- ation of our previous work on the production of strange particles by 7-8-BeV 1r- mesons on hydrogen and carbon. [ 2 - 5 ] The properties of 1r 0 mesons inferred from the y quanta accom- panying A and K 0 production are given, and are compared with the properties of 1r+ and 7r- mesons emitted in A and K 0 production processes. The possibility of a resonance with radi- ative decay is noted.

Pion resonances accompanying strange particle production in 7.5 GeV $\pi^- -p$ interactions

Belyakov, V.A. ; Veksler, V.I. ; Viryasov, N.M. ; et al.
Sov.Phys.JETP 19 (1964) 1326-1332, 1964.
Inspire Record 1387584 DOI 10.17182/hepdata.17001

The simultaneous production of pion resonances and strange particles was investigated. The simultaneous production of p 0 mesons and A-K pairs was observed in events characterized by charged particle multiplicity ns = 4 and having cross sections upo = 20 ± 8 ~b. Cross sections for the production of w and YJ resonances are presented. The 1340-MeV peak in the distribution of four-pion effective masses is discussed.

POLARIZED CROSS-SECTION MEASUREMENTS FOR THE REACTION PI- P ---> ETA N FROM 1171-MEV/C TO 2267-MEV/C AND A PARTIAL WAVE ANALYSIS OF THIS REACTION IN THE RESONANCE REGION

Baker, R.D. ; Brown, Robert M. ; Clark, A.G. ; et al.
Nucl.Phys.B 156 (1979) 93-110, 1979.
Inspire Record 146768 DOI 10.17182/hepdata.34678

Polarized cross sections for the reaction π − p → η n have been measured at 12 incident momenta between 1171 and 2267 MeV/ c . The data show that the polarization is small in the forward direction and there is a general trend for it to be large and positive near cos θ ∗ = 0.2 . These are the first published results on polarization effects in this channel in the resonance region. An energy-dependent partial-wave analysis has been performed and the couplings and branching fractions for decays of nucleon resonances to this channel are presented.

Nucl.Phys.B 153 (1979) 89-111, 1979.
Inspire Record 146579 DOI 10.17182/hepdata.34682

Differential cross sections for the reaction π − p→ η n at 20 incident pion momenta between 724 and 2723 MeV/ c are presented. The results are compared with previous measurements. The data show clear evidence of non-zero couplings of this channel to known I = 1 2 , S = 0 baryon resonances with masses up to 2000 MeV/ c 2 .

Polarization Measurements in $\pi^- p$ Charge Exchange Scattering From 617-{MeV}/$c$ to 2267-{MeV}/$c$

Nucl.Phys.B 144 (1978) 287-311, 1978.
Inspire Record 130405 DOI 10.17182/hepdata.8173

Results are presented of polarization parameter measurements for the reaction π − p→ π 0 n at 22 momenta between 617 and 2267 MeV/ c . These results are generally in agreement with those of previous measurements and in qualitative agreement with predictions of phase-shift analyses. Together with the recently published differential cross-section measurements, they provide a comprehensive set of data for this reaction in the resonance region.

Results are presented of differential cross-section measurements for the reaction π − p→ π 0 n; π 0 → γγ at 22 incident pion momenta between 618 and 2724 MeV/ c . The results are in good agreement with those of other experiments.

Inspire Record 90870 DOI 10.17182/hepdata.6743

This paper presents the results of a counter experiment at the Rutherford Laboratory, in which the polarization parameter in π + p elastic scattering was measured. Data were taken at 64 incident pion momenta between 0.60 and 2.65 GeV/ c . The results are found to be in generally good agreement with those of other experiments, and have substantially higher precision at many momenta.
