Invariant cross-sections for the inclusive reactions $$\bar pp \to \pi ^ + + X$$ and $$\bar pp \to p + X$$ at 22.4 GeV/cat 22.4 GeV/c

Is There a Hierarchy of the Hadron LowpT Spectra?

“…A0 to the behaviour of b as a fimction of pint, no apparent regularity is observed betweenp,,, = 8.25 GeV/c [138] and pinc = 406 GeV/c [82] in X* data (the only sufficient sample of fits). The only rule one can deduce from tables (10, [12][13][14][15][16][17]19) is that with increaaing particle mass the b value decreases. However this has to be taken with caution 8s the x dependence of b and the background influence are difficult to account properly.…”
