Inclusive $\pi^0$ Production in $\pi^+ p$, $K^+ p$ and $p p$ Interactions at 250-{GeV}/$c$

Data are presented on inclusive π0 production in the forward c.m. hemisphere (xF>0.025) in π+p,K+p andpp interactions at 250 GeV/c. These data are compared to results at other energies and interpreted in terms of quark-parton models.

A Measurement of Direct Photon Production at Large P(T) at the {CERN} {ISR}

Diakonou, M. ; Kourkoumelis, C. ; Resvanis, L.K. ; et al.
Phys.Lett.B 91 (1980) 296-300, 1980.
Inspire Record 152520 DOI 10.17182/hepdata.27234

We have measured direct photon production in pp collisions at the CERN intersecting storage rings for c.m. energies 31 < √ s < 63 GeV and transverse momenta up to 9GeV/ c , using segmented lead/liquid-argon calorimeters. The ratio of direct photon to π 0 production is significantly larger than zero, starting at p T ≈ 4 GeV/ c and increasing to values of about 0.4 at 9GeV/ c . No significant √s dependence is seen.

Inclusive High {P(T)} $\omega^0$ and $\eta{'}$ Production at the {ISR}

Diakonou, M. ; Kourkoumelis, C. ; Resvanis, L.K. ; et al.
Phys.Lett.B 89 (1980) 432-436, 1980.
Inspire Record 143931 DOI 10.17182/hepdata.27254

The inclusive production cross section of ω 0 and η′ were measured at transverse momenta of 3 to 7GeV/ c at 90° in the centre of mass. The ω 0 /π 0 and η′/π 0 production ratios were found to be 0.87 ± 0.17 and 0.9 ± 0.25, respectively, at 3.5 GeV and constant up to 7 GeV/ c . The large meson/ π 0 production ratio supports the hypothesis that high- p T mesons are the leading fragments of the basic constituent jet. The η ′/ η ratio exemplifies the SU(3) singlet nature of the η ′.

Direct Production of High $p_T$ Single Photons at the {CERN} Intersecting Storage Rings

The Athens-Athens-Brookhaven-CERN collaboration Diakonou, M. ; Kourkoumelis, C. ; Resvanis, L.K. ; et al.
Phys.Lett.B 87 (1979) 292-296, 1979.
Inspire Record 143254 DOI 10.17182/hepdata.27293

Single photon production in pp collisions at 30 < √ s < 62 GeV has been measured with liquid-argon-lead calorimeters at the CERN ISR. This process remains approximately constant with increasing √ s . For fixed √ s , the single photon to π 0 ratio increases strongly with increase in p T . The γ π 0 ratio is about 0.2 for p T above 4.5 GeV/c.
