Hadron-hadron and hadron-nuclei collisions at high energies
In the 1960’s-1980’s high quality secondary beams became available at proton synchrotrons of increasing energies (PS, AGS, IHEP, FNAL, SPS). The secondary charged hadron beams contained the six stable or quasi stable charged particles π, K, p, p. The main experimental lines of research were: i) total hadron–hadron (hh) cross section measurements at high energies (plab > 20 GeV/c); ii) elastic h...
متن کاملHadron-nuclei collisions at high energies
A brief historical review is made of the hadron-hadron (hh) total cross section and hadronnucleus absorption cross section measurements, made mainly at high energy proton synchrotrons. Then I shall discuss low pt processes, including diffraction processes and fragmentation of nuclei in nucleusnucleus collisions. Nucleus-nucleus collisions at higher energy colliders are then considered, mainly i...
متن کاملLimiting fragmentation in hadron-hadron collisions at high energies
Limiting fragmentation in proton-proton, deuteron-nucleus and nucleusnucleus collisions is analyzed in the framework of the Balitsky-Kovchegov equation in high energy QCD. Good agreement with experimental data is obtained for a wide range of energies. Further detailed tests of limiting fragmentation at RHIC and the LHC will provide insight into the evolution equations for high energy QCD.
متن کاملResonant Slepton Production in Hadron–Hadron Collisions
We consider the resonant production of sleptons via 6Rp in hadron–hadron collisions followed by supersymmetric gauge decays of the sleptons. We look at decay modes which lead to the production of a like-sign dilepton pair. The dominant production mechanism giving this signature is the resonant production of a charged slepton followed by a decay to a charged lepton and a neutralino which then de...
متن کاملOn the universality of cross sections of hadron -hadron(nuclei) collisions at superhigh energies
We analyze the pattern of the onset of complete absorption (the black limit) in the high energy hadron-hadron collisions. The black limit arises due to the hard and soft interaction dynamics as a function of the impact parameters b. Both hard and soft mechanisms provide universal dependence of the partial amplitude of the high energy elastic hadronhadron scattering on the impact parameter b and...
