Baryon stopping in high energy collisions and the extrapolation of hadron production models to Cosmic Ray energies
A new striking feature of hadron production in nuclear collisions is the large stopping of the participating nucleons in hadron–nucleus and nucleus–nucleus collisions. This enhanced baryon stopping can be understood introducing new diquark breaking mechanisms in multistring models of hadron production. Here we show, that similar diquark breaking mechanisms occur at high energy even in hadron–ha...
متن کاملElastic Cross sections for high energy hadron-hadron scattering
This report discusses some results on differential cross sections for high energy and small momentum transfer elastic hadron-hadron scattering in QCD, using a functional integral approach. In particulary a matrix cumulant expansion for the vacuum expectation values of lightlike Wegner-Wilson loops, which governs the hadronic amplitudes, is presented. The cumulants are evaluated using the model ...
متن کاملEnergy spectra of cosmic-ray nuclei at high energies
We present new measurements of the energy spectra of cosmic-ray nuclei from the second flight of the balloon-borne experiment CREAM (Cosmic Ray Energetics And Mass). The instrument included different particle detectors to provide redundant charge identification and measure the energy of cosmic rays up to several hundred TeV. The measured individual energy spectra of C, O, Ne, Mg, Si, and Fe are...
متن کاملAsymptotic properties of high-pT particle production in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions at high energies
The concept of z-scaling reflecting the general features of internal particle substructure, constituent interaction and mechanism of real particle formation is reviewed. Experimental data on the cross sections obtained at ISR, SpS and Tevatron are used in the analysis. The properties of data z-presentation, the energy and angular independencies, the power law, Aand F -dependencies, are discusse...
متن کاملNew analyticity constraints on the high energy behavior of hadron-hadron cross sections
We here comment on a series of recent papers by Igi and Ishida[K. Igi and M. Ishida, Phys. Lett B 622, 286 (2005)] and Block and Halzen[M. M. Block and F. Halzen, Phys. Rev D 72, 036006 (2005)] that fit high energy pp and p̄p cross section and ρ-value data, where ρ is the ratio of the real to the imaginary portion of the forward scattering amplitude. These authors used Finite Energy Sum Rules an...
