THE REACTION ANTI-P P ---> DELTA (1236) ANTI-DELTA (1236) AT BEAM MOMENTA OF 7.23-GEV/C AND 12.0-GEV/C

The reactionp→Δ(1236)\(\bar \Delta \)(1236) is studied at 7.23 GeV/c and at 12GeV/c in terms of the OPE model of Wolf. Good agreement between the model and experimental data is found for the mass andt distributions whereas for decay angular distributions the agreement is less satisfactory. A modified model, allowing for a spin orbit coupling, gives good agreement also for the angular distribution.

Inclusive $\rho^0$, $K^*$+- (892) and F Production in $\bar{p} p$ Interactions at 12-{GeV}/$c$

Inclusive production of ϱ0,K*±(892), andf is studied in\(\bar p\)p interactions at 12 GeV/c. The inclusive cross sections for ϱ0,K*±(892), andf are found to be 6.7±0.3 mb, 1.0±0.2 mb, and 1.4±0.3 mb, respectively. The differential cross sections are presented as a function of c.m. rapidity, Feynmanx and square of the transverse momentumpT2. Comparison with the correspondingpp data shows some interesting differences which can be attributed to the\(\bar p\)p annihilation. The results are compared with the predictions of the quark fusion model.

INCLUSIVE SIGMA+- (1385) PRODUCTION IN anti-p p INTERACTIONS AT 12-GeV/c

Karimaki, V. ; Kinnunen, R. ; Korkea-aho, M. ; et al.

Inclusive production of∑±(1385) resonances is studied in\(\bar pp\) interactions at 12 GeV/c. The cross sections for∑+(1385)+cc and∑− are determined to be 251±38 μb and 123±30 μb, respectively. The inclusive spectra are presented as a function of Feynman x, c.m. rapidity and the squared transverse momentumpT2. Significant differences with the correspondingpp data are found in the longitudinal momentum distributions. The qualitative features of the production can be explained by simple quark ideas.

General Features of the Anti-p $p$ Interaction at 12-{GeV}/c

Simple inclusive cross sections for p p interactions at 12 GeV/ c are given. The data cover prong cross sections, V 0 production and resonances. Separation has been made into annihilation and non-annihilation modes. Some implications of the data are discussed. It is pointed out that the ratios of cross sections for ϱ 0 π − production are independent of incident antiproton momentum in p p annihilation processes, and that data at the highest available pp energies (ISR) tend to the same value.
