NC, CF, and TF are the color factors for SU(N) group. For SU(3) they are equal to: NC = 3, CF = 4/3, and TF = 1/2.


A Measurement of the pi0, eta and eta-prime electromagnetic form-factors

The CELLO collaboration Behrend, H.J. ; Criegee, L. ; Field, J.H. ; et al.
Z.Phys.C 49 (1991) 401-410, 1991.
Inspire Record 299282 DOI 10.17182/hepdata.45172

We present measurement of the π0γ*γ, ηγ*γ and η′γ*γ form factors. The π0-form factor is for the first time observed in the space-like region. The transition form factor of the η-meson is determined from its decay modes π+π−π0, π+π−γ and the neutral decay mode γγ. The decay of the η′ is observed in the decay channels ργ, ηπ+π− with η→γγ and in the four charged prong final state stemming from ηπ+π− with the η decaying into π+π−(π0/γ). All form factors agree well with a simple ρ-pole predicted by the vector meson dominance model and also with the QCD inspired Brodsky-Lepage model.

Energy Dependence of the Pseudorapidity Distributions in Proton-Nucleus Collisions Between 50-GeV/c and 200-GeV/c.

Halliwell, C. ; Elias, J.E. ; Busza, W. ; et al.
Phys.Rev.Lett. 39 (1977) 1499-1502, 1977.
Inspire Record 123287 DOI 10.17182/hepdata.21004

Pseudorapidity distributions for proton-nucleus interactions are presented. The data cover twelve nuclei ranging from carbon to uranium and three incident proton momenta, 50, 100, and 200 GeV/c.
