Photon Multiplicity Measurements : From SPS to RHIC and LHC
نویسنده
چکیده
Abstract. Results from the photon multiplicity measurements using a fine granularity preshower photon multiplicity detector (PMD) at CERN SPS are discussed. These include study of pseudorapidity distributions of photons, scaling of photon multiplicity with number of participating nucleons, centrality dependence of < pT > of photons, event-by-event fluctuations in photon multiplicity and localised charged-neutral fluctuations. Basic features of the PMD to be used in STAR experiment at RHIC and in ALICE experiment at LHC are also discussed.

Glauber Monte-Carlo predictions for LHC
In the framework of various Glauber-like models we compute several correlation observables in nuclear collisions at the SPS, RHIC, and LHC energies. We analyze fluctuations of the eccentricity of the fireball created in the collision, in particular the variable-axes harmonic moments ε∗, as well as the fluctuations of multiplicity of charged particles. We find moderate model dependence of the sc...
متن کاملCentrality dependence of the multiplicity and transverse momentum distributions at RHIC and LHC and the percolation of strings
The dependence of the multiplicity and the transverse momentum distribution on the number of collisions are studied for central and peripheral Au-Au collisions at SPS, RHIC and LHC energies in the framework of percolation of strings. A scaling law relating the multiplicity to the mean transverse momentum is obtained. Our results are in overall agreement with the SPS and RHIC data, obtaining a s...

New experimental data on inclusive spectra of identified particles produced in pp collisions at the RHIC are used to test z-scaling. Energy and multiplicity independence of the scaling function is established. The RHIC data confirm z-scaling observed at U70, ISR, SpS and Teva-tron energies. The obtained results are of interest to search for new physics phenomena of particle production in high t...
متن کاملStatistical hadronization of charm in heavy-ion collisions at SPS, RHIC and LHC
We study the production of charmonia and charmed hadrons in nucleus-nucleus collisions at SPS, RHIC, and LHC energies within the framework of the statistical hadronization model. Results from this model are compared to the measured yields and centrality dependence of J/ψ production at SPS and RHIC energies. We explore and contrast the centrality dependence of the production of mesons with open ...

We study the production of charmonia and charmed hadrons for nucleus-nucleus collisions at SPS, RHIC, and LHC energies within the framework of the statistical hadronization model. Results from this model are compared to the observed centrality dependence of J/ψ production at SPS energy. We further provide predictions for the centrality dependence of the production of open and hidden charm meson...
