“…This peak is absent from the Aguilar-Benitez et al data due to trigger inefficiency for x F > 0.75 in this particular experiment[21].…”

“…Figure 1: Inclusive spectrum for the reactions pp → pX and pp →pX (in the insert). Data from [1,21,22]. The solid curves are the results of the fit described in the text calculated for 400 GeV /c.…”

“…Experimental data on leading particle spectrum are very scarce. A compilation for pp → pX is shown in Fig.1 where data from three experiments [1,21,22] are put together (the curve and the insert in this figure should be ignored for the moment). As can be seen, a pretty flat spectrum is exhibited, except for x F ≈ 1 where the typical diffractive peak appears.…”

Neutral pions and η mesons as probes of the hadronic fireball in nucleus-nucleus collisions around1AGeV

“…Within each reaction the π 0 and η spectra exhibit almost identical inverse-slope parameters T B which in addition do not change significantly with the mass of the colliding nuclei. Such a behaviour, the so-called m t scaling, is well known in high-energy physics [34,35]. Having in mind the different production mechanisms for both meson species it is furthermore quite remarkable that for m t ≥ m η the π 0 and η data roughly fall on one commen line for all systems.…”

Hadroproduction ofφ-mesons in the quark-gluon string model

“…In the model under consideration it is possible to improve the description of the experimental data [7] by slightly changing the value of the a 1 parameter in the fragmentation functions of the s-quark (3) and ds-diquark (8). However for the exact determination of the quark and diquark fragmentation functions into the D s -mesons more precise measurements of all observations are needed: total and differential cross sections and leading/nonleading production asymmetry especially at large x F .…”
