Confinement and Entropy in Heavy Ion Collisions
In heavy ion collisions the evolution of hadronic fireball was successfully described by the hadrochemical model [1]. This model is based on elementary processes in which hadronhadron collisions lead to the production of other type of hadrons. The time-evolution of the hadronic system was described by a set of coupled differential equations in which the time-dependent gain and loss terms were d...
متن کاملMeasuring an entropy in heavy ion collisions
which is central in a thermodynamical description. Out of four observables entering above equation (energy E, multiplicity n and temperature T ), the entropy S is most difficult to directly measure in experiment. In this talk the recent proposal to determine entropy experimentally is discussed [1]. The Boltzmann relation S(E, n) = log Γ(E, n) reduces the problem to measuring the density of stat...
متن کاملShannon Information Entropy in Heavy-ion Collisions
The general idea of information entropy provided by C.E. Shannon “hangs over everything we do” and can be applied to a great variety of problems once the connection between a distribution and the quantities of interest is found. The Shannon information entropy essentially quantify the information of a quantity with its specific distribution, for which the information entropy based methods have ...
متن کاملd ′ production in heavy ion collisions
The production of d′ dibaryons in heavy ion collisions due to the elementary process NN → d′π is considered. The NN → d′π cross section is estimated using the vacuum d′ width Γd′ ≈ 0.5 MeV extracted from data on the double charge exchange reactions on nuclei. The d′ production rate per single collision of heavy ions is estimated at an incident beam energy of 1 A·GeV within the framework of the ...
متن کاملStrange Baryon Production in Heavy Ion Collisions
The rapidity distribution of Λ and Λ̄ produced in nucleus-nucleus collisions at CERN energies is studied in the framework of an independent string model with quark-antiquark as well as diquark-antidiquark pairs in the nucleon sea. It is shown that, besides the Λ-Λ̄ pair production resulting from the fragmentation of sea diquarks, final state interactions of co-moving secondaries π +N → K + Λ and ...
