Centrality control of hadron-nucleus interactions by detection of slow nucleons

نویسنده

  • Ferenc Siklér
چکیده

Slow nucleons emitted during a hadron-nucleus interaction can give information on the centrality, impact parameter of the collision. The aim of this note is to provide the reader with the important characteristics of the slow nucleons, focusing on their spectra, correlations. This study tries to build on evidences, hence more weight is put on experimental results than on models.

Shadowing Effects on the Nuclear Suppression Factor, RdAu, in d+Au Interactions

We explore how nuclear modifications to the nucleon parton distributions affect production of high transverse momentum hadrons in deuteron-nucleus collisions. We calculate the charged hadron spectra to leading order using standard fragmentation functions and shadowing parameterizations. We obtain the d+Au to pp ratio both in minimum bias collisions and as a function of centrality. The minimum b...

On 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...

Studies of Nucleon-Gold Collisions at 200 GeV per Nucleon Pair Using Tagged d+Au Interactions

The spectra of charged hadrons produced near mid-rapidity in d+Au, p+Au and n+Au collisions at p sNN = 200 GeV are presented as a function of transverse momentum and centrality. Thesemeasurements were performed using the PHOBOS detector at the Relativistic Heavy Ion Collider (RHIC). Nucleon-nucleus interactions were extracted from the d+Au data by identifying the deuteron spectators. The deuter...

Hadronic Interactions for High Energy Cosmic Ray Air Showers

Understanding hadronic interactions at high energies represents a very important ingredient for modeling high energy cosmic ray air showers. In this paper, we present a new approach to simulate hadronic interactions, including hadron-hadron, hadron-nucleus, and nucleus-nucleus scattering, in the energy range roughly between 10 11 and 10 17 eV. Such collisions are very complex, being composed of...

Coherent Interactions in Nucleus- Nucleus Collisions

At the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory and at the Large Hadron Collider (LHC) at CERN, particles will be produced in coherent and diffractive nuclear interactions. In extremely peripheral nuclear collisions (b>2R), coherent interactions occur at very high rates and are dominated by photonPomeron or photon-meson processes. In these reactions, the photon a...
