One of the key signatures of the Quark-Gluon Plasma (QGP), is the modification of hadron transverse momentum differential cross-sections in heavy-ion collisions (HIC) as compared to proton-proton (pp) collisions. Suppression of hadron production at high transverse momenta ($p_{\mathrm{T}}$) in HIC has been explained by the energy loss of the partons produced in the hard scattering processes...

Measurements of non-photonic electron(NPE) production at RHIC show similar suppression as light hadrons at high pT in central Au+Au collisions with respect to scaled p+p collisions. However, the interpretation is complicated by the combined contributions from charm and bottom decays. It is important to separate out the bottom contribution for a better understanding of heavy flavor production...

We analyze the transverse-momentum spectra of strange hadrons produced in Pb + Pb collisions at the collision energy √{sNN}=2.76 TeV for different centrality bins. Our approach combines the concept of chemical nonequilibrium with the single-freeze-out scenario. The two ideas are realized in the framework of the Cracow model, whose thermodynamic parameters have been established in earlier...

Dielectrons are a unique tool to probe several stages of the space-time evolution of the hot and dense system created in ultra-relativistic heavy-ion collisions. They carry unaffected information since once produced they escape the medium with negligible final-state interaction. The low-mass region of the dielectron spectrum (m $<$ m$_{\rho}$) is interesting to study virtual direct photons...

108. Scaling properties of the mean multiplicity and pseudorapidity density \\ in $e^{-}+e^{+}$, $e^{\pm}$+p, p($\bar{\mathrm{p}}$)+p, p+A and A+A(B) collisions

The pseudorapidity density ($dN_\mathrm{ch}/d\eta$) for p($\bar{\mathrm{p}}$)+p, p+A and A+A(B) collisions, and the mean multiplicity $\langle N_\mathrm{ch}\rangle$ for $\mathrm{e^- + e^+}$, $\mathrm{e^{\pm}+p}$, and p($\bar{\mathrm{p}}$)+p collisions, are studied for an inclusive range of beam energies ($\sqrt{s}$). Characteristic scaling patterns are observed for both...
