Leading proton and antiproton distributions in proton-nucleus and antiproton-nucleus interactions

Constituent quark model for nuclear stopping in high energy nuclear collisions

“…2. The calculated cross sections are in good agreement with the experimental values [19,25]. The process of one quark interaction with the probability P (1) pA is dominant for light nuclei.…”

“…In addition to pp → pX of Ref. [18], we use data on pCu → pX and pAg → pX provided by two experimental groups [19,27] in order to cover the wide x range. As Ref.…”

“…[19] in the range 0.3 < x < 0.6 where there exist data points from both groups. Such a procedure is possible because the x-dependence of a fixed p T -cross section of [27] is really similar to xdσ/dx of [19] as shown in Figs. 6 (c) and (d).…”

“…The flavor factor is introduced to make a distinction whether a final state baryon is an observed proton, a neutron or a nucleon decayed from a hyperon. The determination of fragmentation function f i (x) comes from fitting the data on proton-proton [18] and protonnucleus collision [19]. This paper is organized as follows.…”

Inelasticity inp-nucleus collisions and its application to high energy cosmic-ray cascades

“…The data we use to study inelasticity are inclusive proton spectra from p + nucleus reactions by Barton et al [20] and Bailey et al [22] with beam energies of 100 and 120 GeV respectively. The 100 GeV data were collected for C, Al, Cu, Ag, and Pb targets for two transverse momentum bins of 0.3 and 0.5 GeV/c.…”
