Feynman scaling
WebJun 24, 2014 · All CR models indicate deviations from scaling for the forward photons, such that the production rate decreases with increasing \(W\). In particular, this effect is strong for the SIBYLL 2.1 and QGSJET 01 models. For forward neutrons the CR models are consistent with Feynman scaling, with exception of SIBYLL 2.1. WebNov 1, 1994 · Abstract. The Feynman scaling law regarding the inclusive energy spectrum in multiparticle production, seeming to be valid in the low energy region √s ≪ 63 GeV, is examined in the high energy region by analyzing the data of the UA5 and UA7 collaborations at the CERN SPS p p.
