EPJ A Hadrons and Nuclei

چکیده
We work out a superstatistical description of high-energy scattering processes that takes into account temperature fluctuations in small-volume elements. For Γ -distributed fluctuations of the inverse temperature one effectively obtains a generalized statistical mechanics of Tsallis type, whereas for other temperature distributions more general superstatistical models arise. We consider two main examples: Scattering processes of cosmic ray particles and ee annihilation processes. In both cases one obtains excellent fits of experimentally measured energy spectra and cross-sections. PACS. 96.50.sb Composition, energy spectra and interactions – 12.40.Ee Statistical models

EPJ A Hadrons and Nuclei
In the context of the Hagedorn temperature half-centenary I describe our understanding of the hot phases of hadronic matter both below and above the Hagedorn temperature. The first part of the review addresses many frequently posed questions about properties of hadronic matter in different phases, phase transition and the exploration of quark-gluon plasma (QGP). The historical context of the di...
متن کاملHighlights of the ISOLDE facility and the HIE-ISOLDE Project
The ISOLDE Radioactive Beam Facility is the dedicated CERN installation for the production and acceleration of radioactive nuclei far from stability. Exotic nuclei of most chemical elements are available for the study of nuclear structure, nuclear astrophysics, fundamental symmetries and atomic physics, as well as for applications in condensed-matter and life sciences. Since more than a decade ...
متن کاملSmall x Gluons in Nuclei and Hadrons
We numerically study the effects of high gluon density at small x on the evolution of gluon distribution function in both hadrons and nuclei. Using a newly derived, Wilson renormalization group-based evolution equation which includes n to 1 gluon ladder fusion, we find significant reduction in nuclear gluon distribution function for large nuclei at zero impact parameter at energies relevant for...
متن کاملPseudospin Symmetry as a Bridge between Hadrons and Nuclei
Atomic nuclei exhibit approximate pseudospin symmetry. We review the arguments that this symmetry is a relativistic symmetry. The condition for this symmetry is that the sum of the vector and scalar potentials in the Dirac Hamiltonian is a constant. We give the generators of pseudospin symmetry. We review some of the predictions that follow from the insight that pseudospin symmetry has relativi...
متن کاملHard exclusive wide-angle processes
In this talk the handbag approach to hard exclusive wide-angle processes is reviewed and applications, as for instance two-photon annihilations into pairs of mesons, are discussed. 1 Handbag factorization Factorization properties of QCD allow us to calculate exclusive processes provided a hard scale is available, either the three Mandelstam variables s,−t,−u are large as compared to a typical h...
