Study of $\omega \omega$ Systems Produced in 38-{GeV}/$c \pi^- p$ Collisions

The π − p→ ωω n reaction has studied for the first time at the 70 GeV IHEP accelerator. The six photons from the decay of the two ω mesons were detected in GAMS-2000, a hodoscope multi-photon spectometer. Two resonances decaying into ωω,X (1640) and X(1960), have been observed. Their quantum numbers are J PC =2 ++ , I G =0 + . The reaction is dominated by the one-pion exchange mechanism. The production cross sections σ. BR(X→ ωω ) are 0.65±0.15 μ b and 1.0±0.2 μ b, respectively.

Two Particle Correlations in Inclusive and Semiinclusive pi- p Reactions at 200-GeV/c

Biswas, N.N. ; Bishop, J.M. ; Cason, N.M. ; et al.
Phys.Rev.Lett. 35 (1975) 1059, 1975.
Inspire Record 2906 DOI 10.17182/hepdata.3351

Significant two-particle correlations of dynamical origin are observed in 200 GeV/c π−p inclusive interactions. This is demonstrated by comparison with kinematic correlations calculated from an independent-particle-emission model. Two distinct correlation types are observed: (a) unlike-particle correlations with correlation length ∼ 1.3 rapidity units independent of azimuthal separation, and (b) like-particle correlations with correlation length ∼ 0.4 rapidity units which are observed only for small azimuthal separations.

Inclusive Delta++ Production in pi+ p and p p Interactions at 100-GeV/c and the Average Multiplicity of pi+ pi- Scattering

Erwin, J. ; Kass, R.D. ; Klems, J.H. ; et al.
Phys.Rev.Lett. 35 (1975) 980, 1975.
Inspire Record 2415 DOI 10.17182/hepdata.21100

Inclusive Δ++(1236) production in π+p and pp interactions is consistent with one-pion exchange. The average charged multiplicity recoiling from the Δ++ is studied as a function of missing mass, M2, for both interactions.

A structure has been observed at 2220 MeV in the mass spectrum of ηη ′ systems produced by 38GeV/ c and 100 GeV/ c ′ negative pions on protons. The angular distribution of the decay products shows that this structure is presumably a spin J ⩾ 2 meson.
