Statistical Model Predictions for Pb-Pb Collisions at LHC

The systematics of Statistical Model parameters extracted from heavy-ion collisions at lower energies are exploited to extrapolate in the LHC regime. Predictions of various particle ratios are presented and particle production in central Pb-Pb collisions at LHC is discussed in the context of the Statistical Model. The sensitivity of several ratios on the temperature and the baryon chemical pote...

HYDJET++ simulations and reconstruction of the anisotropic flow in Pb+Pb collisions at the LHC

The azimuthal anisotropy of charged particles in heavy ion collisions is an important probe of quark-gluon plasma evolution at early stages. In the present paper the elliptic flow pattern in Pb+Pb collisions at √ s = 5.5 TeV is analyzed for different hadron species in the frameworks of HYDJET++ Monte-Carlo model. The influence of resonance decays on particle flow is investigated. The different ...

ALICE diffractive physics in p-p and Pb-Pb collisions at the LHC

The ALICE experiment at the Large Hadron Collider LHC is presently being commissioned. ALICE consists of a central barrel, a muon spectrometer and neutron calorimeters at 00. Additional detectors for event classification and trigger purposes are located on both sides of the central barrel. The geometry of the ALICE detector allows the implementation of a diffractive double gap trigger by requir...

high-pT hadron spectra in nearly central Pb+Pb collisions at the LHC

We study the hadron spectra in nearly central A+A collisions at RHIC and LHC in a broad transverse momentum range. We cover the low-pT spectra using longitudinally boost-invariant hydrodynamics with initial energy and net-baryon number densities from the perturbative QCD (pQCD)+saturation model. Build-up of the transverse flow and sensitivity of the spectra to a single decoupling temperature Td...

Measuring beauty production in Pb–Pb collisions at the LHC via single electrons in ALICE

The ALICE experiment [1] will study proton–proton, proton–nucleus and nucleus– nucleus collisions at the LHC, with centre-of-mass energies per nucleon–nucleon (NN) pair, √ sNN, of 5.5 TeV for Pb–Pb, 8.8 TeV for p–Pb, and 14 TeV for pp. The primary physics goal of ALICE is the study of the properties of QCD matter at the energy densities of several hundred times the density of atomic nuclei that...
