Results are presented on inclusive production of resonant and non-resonant particle systems produced inK+p interactions at 32 GeV/c. We compareK*+(892),$\bar \Sigma ^{ *- } $(1385), Σ*±(1385), and ϱ0 inclusivex-spectra with the ones of non-resonantKs0π±,$\bar \Lambda \pi ^ -$, Λπ± and π+π− pairs at the same effective mass. Resonance-particle pairsK*+π±, Σ*+π−, and$\bar \Sigma ^{ *- } \pi ^ -$ are also studied together with non-resonant tripletsKs0π±, Λπ+π−,$\bar \Lambda \pi ^ -\pi ^ -$. The invariantx-spectra of resonant particle pairs decrease less rapidly withx then the corresponding non-resonant pairs. Comparison with quark-recombination predictions indicates that the particles, resonances and multiparticle systems are probably created off a single valence quark or diquark instead of carrying all possible valence-quarks.

Azimuthal Asymmetry in Inclusive Hadron Production by e+ e- Annihilation

Schwitters, R. ; Boyarski, A. ; Breidenbach, Martin ; et al.

Phys.Rev.Lett. 35 (1975) 1320, 1975.

Inspire Record 100683 DOI 10.17182/hepdata.21192

We have observed an azimuthal asymmetry in inclusive hadron production by e+e− annihilation at the center-of-mass energy s=7.4 GeV. The asymmetry is caused by the polarization of the circulating beams in the storage ring and allows separate determination of the transverse and longitudinal structure functions. We find that transverse production dominates for x>0.2 where x is the scaling variable 2ps.

Difference of nonannihilation anti-p p interactions at 22.4-GeV/c from p p interactions at close energy

Batyunya, B.V. ;

JINR-1-89-28, 1989.

Inspire Record 292242 DOI 10.17182/hepdata.54979

The longitudinal and transverse momentum distributions of protons and π±-mesons, produced and pp interactions at close energy (22-24 GeV), are compared. The existence of a difference between these (P<1.2 GeV/c in laboratory system) and for mesons accompaying them, is shown. The observed difference increases with increasing the multiplicity of charged particles. For π+ mesons it increases with decreasing the momentum of accompaying protons. These effects do not practically exist for π- mesons

Eta and omega Meson Production in Medium-Energy pi+- p and K- p Interactions

The Aachen-Berlin-Bonn-CERN-Cracow-London-Vienna-Warsaw collaboration Bartke, J. ; Kirk, H. ; Kaltwasser, J. ; et al.

Nucl.Phys.B 118 (1977) 360-370, 1977.

Inspire Record 110525 DOI 10.17182/hepdata.48967

The production of η(550) and ω(780) mesons is studied in π ± p interactions at 16 GeV/ c and K − p interactions at 10 and 16 GeV/ c . Cross sections for exclusive channels are presented, and for the π + p data differential cross sections are given for quasi-inclusive production where the η or ω is required to be accompanied by charged particles only. Close similarities are observed between η, ω and also ϱ 0 (770) production in terms of longitudinal and transverse variables. By a rough estimate, the η, ω and ϱ 0 inclusive yields are found to be in the ratio 0.32 : 0.85 : 1, respectively, for 16 GeV/ c π + p collisions. For non-peripheral production we estimate this same ratio to be 0.34 : 0.9 : 1.
