Production of gamma rays in K- p and K+ p Interactions at 32-GeV/c

The French-Soviet & CERN-Soviet collaborations Beilliere, P. ; Cochet, Christian ; Dumont, J J ; et al.
Nucl.Phys.B 91 (1975) 219-231, 1975.
Inspire Record 2852 DOI 10.17182/hepdata.6709

Inclusive cross sections and longitudinal momentum distributions are presented for γ rays produced in K − p and K + p interactions at 32 GeV/c in the 4.5 m Mirabelle hydrogen bubble chamber at the Serpukhov accelerator. The average longitudinal and transverse momentum of neutral pions and the average π 0 multiplicity ▪ 〈 n π 0〉 are estimated. It is found that 〈 n π 0〉 is an increasing function of the number of charged prongs.

Inclusive Production of Y* Resonances in K- p Interactions at 14.3-GeV/c

Bardadin-Otwinowska, M. ; Barloutaud, R. ; Borg, A. ; et al.
Nucl.Phys.B 98 (1975) 418-428, 1975.
Inspire Record 99415 DOI 10.17182/hepdata.31900

The inclusive production of Σ + (1385), Σ − (1385), Λ (1405) and Λ (1523) in K − p interactions at 14.3 GeV/ c is studied. Cross sections are presented and the x dependence of the invariant cross sections is discussed. The density matrices for production of the spin- 3 2 resonances at small momentum transfer to the target are consistent with spin-0 exchange.

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

Barish, S.J. ; Derrick, M. ; Musgrave, B. ; et al.
Phys.Rev.D 12 (1975) 1260, 1975.
Inspire Record 98475 DOI 10.17182/hepdata.24865

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.

Inclusive Production of Charged and Neutral Sigma Hyperons in K- p Interactions at 14.3-GeV/c

Bardadin-Otwinowska, M. ; Borg, A. ; Pierre, F. ; et al.
Nucl.Phys.B 90 (1975) 397-409, 1975.
Inspire Record 91429 DOI 10.17182/hepdata.6740

Inclusive production of Σ + , Σ − and Σ 0 hyperons in K − p interactions at 14.3 GeV/ c has been studied and compared to Λ production. Cross sections are presented as a function of longitudinal and transverse momenta and compared to the pp → Σ + + anything data.
