“…As far as results from higher energy p+p colliders, basically RHIC at √ s = 200 GeV and LHC at √ s from 900 GeV to 4 Normalization factors introduced for the spectrometer experiments 13 TeV, are concerned, there is a drastic reduction of phase space coverage. As shown in Sect.…”

“…28,29,30,31,32,33,34,35). The case of Sims [13] is special in the sense that the data come from a large exposure of 80k events but only 3 values of p T are given in the publication. The rest is hidden in a parametrization as functions of p T (double Gaussian), y (exponential and Gaussian), and x F (exponential and Gaussian).…”

Over the past 60 years a rich sample of experimental results concerning the inclusive production of $$\pi ^-$$ π - mesons has been obtained spanning a range from about 3 GeV to 13 TeV in interaction energy. This paper attempts a model-independent overview of these results with the aim at obtaining an internally consistent data description on a dense grid over the three inclusive variables transverse momentum, rapidity or Feynman $$x_F$$ x F and interaction energy. The study concentrates on the non-perturbative sector of the strong interaction by limiting the transverse momenta to $$p_T<$$ p T < 1.3 GeV/c. The three-dimensional interpolation which is mandatory and necessary for this aim is shown to provide a controlled systematic precision of better than 5%. This accuracy allows for a critical inspection of each of the 40 experiments concerned in turn. It also allows precision tests of some of the physics concepts developed around inclusive processes like energy scaling, “thermal” production and the evolution of transverse momenta.

“…The B, and R values show more diversity. The value of B1 is sensitive to kinematical region, giving higher values in the central region for LI distributions [16,22,281. I n x+n, pn interactions at 195 GeV/c [27] and pp interactions at 100 GeV/c [25] the B, values are particularly high.…”

“…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.…”

A compilation of fits to the low pT hadron distributions is presented. The universality of the distributions is examined. The pT distributians of direct pions and resonances in the reaction pp → 2π+2π−π0 at 5.7 GeV/c are fitted separately. Indications are found that up to ISR energies there are three types oflow pT inclusive hadron distributions in hadron‐hadron interactions. The inclusive pT distributions of different particles are divided into these three groups according to the particle mass.
