Inclusive $\Delta^{++}$ and $\Lambda$ Production in Proton Proton Interactions at {ISR} Energies

Drijard, D. ; Fabbri, F. ; Fischer, H.G. ; et al.

Inspire Record 188801 DOI 10.17182/hepdata.16280

Inclusive cross sections forΔ++ production inpp interactions at different ISR energies are presented. The differential cross sectiondσ/dx forΔ++ production is found to be approximately independent of Feynmanx. No strong energy dependence is seen over the ISR energy range. The topological cross sections ofΔ++ at\(\sqrt s= 62\) GeV show an appreciable contribution from non-diffractive production mechanisms. An upper limit for theΔ0 production cross section is determined.

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.

Study of the Reaction $pp \to \Delta^{++} (1236) + X^0$ at 205 GeV/c

Barish, S.J. ; Derrick, M. ; Musgrave, B. ; et al.

We have studied inclusive Δ++(1236) production for |tpΔ|<1.0 (GeV/c)2 in a 50 000 picture exposure of the 30-inch hydrogen bubble chamber to a 205 GeV/c proton beam. The inclusive Δ++ cross section for one hemisphere in the center-of-mass system is (1.30±0.14) mb. The mean charged multiplicity of the system recoiling off the Δ++ is in agreement with that for laboratory π−p interactions at the same energy in the center-of-mass frame. The inclusive Δ++ production is compared to inclusive Λ0 and proton production in the same experiment. The connection between Δ++ production and diffraction is discussed. We find that not all Δ++ come from the decay of a diffractively-produced state. The PT2 distribution for the Δ++ has a slope of (10.5±0.9) (GeV/c)−2 for PT2≲0.2 (GeV/c)2. This slope, together with the decay angular distribution of the Δ++ at small momentum transfer, suggests a strong pion-exchange contribution to the inclusive process. We compare the data to the expectation of a triple-Regge model with ρ- and π-exchange contributions.

Differences in Leading Baryon Production From $p \bar{p}$ and $p p$ Collisions With $\sqrt{s}=31$-{GeV} at the {CERN} {ISR}

Chauvat, P. ; Cousins, R.D. ; Erhan, S. ; et al.
Phys.Lett.B 127 (1983) 384-388, 1983.
Inspire Record 190333 DOI 10.17182/hepdata.30717

Significant differences are observed between forward-produced Δ ++ (1232) and Λ 0 's in pp interactions and their corresponding anti-particles in p p interactions, as expected from quark counting and single q q annihilation. A possible relationship between these results and the p p -pp total cross section difference is discussed.
