A thermodynamical model of hadron production in e+e− collisions
نویسنده
چکیده
The hadron production in ee collisions is studied assuming that particles originate in a hadron gas at thermal and chemical equilibrium. The parameters of the hadron gas are determined with a fit to the average multiplicities of various hadron species measured at LEP and PEP-PETRA colliders. An impressive agreement is found between the predictions of this model and data for almost all particles over a range of production rate of four orders of magnitude. The temperature values found at the centre of mass energies of LEP and PEP-PETRA are around 165 MeV. To be published in the Proceedings of the XXV International Symposium on Multiparticle Dynamics

In my talk I want to introduce the thermodynamical analysis of data from (ultrarelativistic)nucleus-nucleus collisions at AGS, SPS and RHIC. A simple thermodynamical model can beused to determine the temperature T and the Baryon chemical potential μB at freeze-outfrom Quark Gluon Plasma to a free Hadron gas. This phase boundary can be investigated byscanning the beam energy ...
متن کاملFian/td-98/24 Minijet Transverse Energy Production in the Next-to-leading Order in Hadron and Nuclear Collisions
The transverse energy flow generated by minijets in hadron and nuclear collisions into a given rapidity window in the central region is calculated in the next-to-leading (NLO) order in QCD at RHIC and LHC energies. The NLO transverse energy production in pp collisions cross sections are larger than the LO ones by the factors of KRHIC ∼ 1.9 and KLHC ∼ 2.1 at RHIC and LHC energies correspondingly...

متن کاملHadron Production in γγ Collisions as a Background for e+e− Linear Colliders
Drees and Godbole have proposed that, at the interaction point of an e+e− linear collider, one expects a high rate of hadron production by γγ collisions, providing an additional background to studies in e+e− annihilation. Using a simplified model of the γγ cross section with soft and jet-like components, we estimate the expected rate of these hadronic events for a variety of realistic machine d...
متن کاملTransverse momentum spectra of identified particles in high energy collisions with statistical hadronisation model
A detailed analysis is performed of transverse momentum spectra of several identified hadrons in high energy collisions within the framework of the statistical model of hadronisation. The effect of the decay chain following hadron generation is accurately taken into account. The considered centre-of-mass energies range from ' 10 to 30 GeV in hadronic collisions (πp, pp and Kp) and from ' 15 to ...
