Review of Structures in the Energy Dependence of Hadronic Observables
The energy dependence of various hadronic observables is reviewed. The study of their evolution from AGS over SPS to the highest RHIC energy reveals interesting features, which might locate a possible onset of deconfinement. These observables include transverse spectra of different particle types and their total multiplicities, as well as elliptic flow. In this context especially the observatio...
متن کاملOn the Energy Dependence of Hadronic B C Production
An estimate is presented of the production cross section of B c mesons between threshold and LHC energies using lowest-order perturbation theory and non-relativistic bound state approximation. It is shown that the ratio of the production cross sections for B c mesons and for b quarks varies strongly with energy.
متن کاملHadronic centrality dependence in nuclear collisions
The kaon number density in nucleus+nucleus and p+p reactions is investigated for the first time as a function of the initial energy density ǫ and is found to exhibit a discontinuity around ǫ=1.3 GeV/fm. This suggests a higher degree of chemical equilibrium for ǫ > 1.3 GeV/fm. It can also be interpreted as reflection of the same discontinuity, appearing in the chemical freeze out temperature (T)...
متن کاملGeneral Theory of Cycle-Dependence of Total pi-Electron Energy
The theoretical treatment of cycle-effects on total pi-electron energy, mainly elaborated by Nenad Trinajstic and his research group, is re-stated in a general and more formal manner. It enables to envisage several other possible ways of measuring the cycle-effects and points at further directions of research.
متن کاملThe Energy Dependence of the Photoelectric Attenuation Coefficient of Substances
Introduction: The photoelectric attenuation coefficient of substances is known to depend upon the energy E of the photon and the effective atomic number of substances (Zeff) as (Zeffx/Ey). No definitive values about these indices x, y are given in the literature. The index x is said to lie between, 3.0 and 4.0, while for ‘y’ different values have been assigned, between 3.0 and 4.0. Method...
