Abstract

It is found that the CERN Intersecting Storage Ring data on pp => π± + X inclusive reactions can be represented by a single scaling variable η = 2p2Tx/(c ln(s/s0)) for 0.075 ≤ x ≤ 0.3 and 0.2 ≤ pT ≤ 1.5 GeV/c. The charge ratio of cosmic pion spectrum at the top of the atmosphere has been estimated using this new type of scaling variable and the primary nucleon spectrum of Grigorov et al. has been used as a hadron source at the top of the atmosphere.
