Hadron thermodynamics and chemistry
Oral Presentation
Identified particle spectra are a basic observable to understand the behaviour of the matter created in high-energy heavy-ion collisions. The transverse momentum distributions of identified hadrons contain informations about the transverse expansion of the system and constrain the freeze-out properties of the matter created. The ALICE experiment has very good particle identification...

Hadron thermodynamics and chemistry
Oral Presentation
We investigate, using the newest LHC data, the energy
dependence of hadron production within the framework of the
statistical hadronization model. The data are confronted with
predictions based on extrapolation from lower (RHIC) energies. While
the yields of hadrons made from light (u,d,s) quarks generally exhibit
little change apart from the overall increase in
multiplicity, a...

Hadron thermodynamics and chemistry
Oral Presentation
The ALICE experiment at the LHC has measured the production of strange hadrons and resonances in Pb-Pb and pp collisions at unprecedentedly high beam energies. The study of strange hadrons and resonances helps us to understand the medium properties and its evolution at dierent stages.
We will present the pT spectra and yields at mid-rapidity for strange hadrons (,
labda, xi, omega, their...

Global and collective dynamics
Oral Presentation
Strange hadron production is sensitive to parton dynamics in nucleus-nucleus collisions. In particular, the strange quark production rate and its subsequent evolution in the dense partonic medium depend on the beam energy and the net baryon density. We will present STAR measurements of $K^{0}_{s}$, $K^{\pm}$, $\phi$, $\Lambda$, $\Xi$, and $\Omega$ at mid-rapidity from Au+Au collisions at...

Hadron thermodynamics and chemistry
Oral Presentation
The excellent particle identification capabilities of the ALICE experiment allow the studies of (anti) matter and hyper-matter production. (Anti) deuterons, tritons, 3He and 4He as well as the corresponding antinuclei can be cleanly identified based on their specific energy loss in the Time Projection Chamber and velocity information in the Time-Of-Flight detector. The (anti) hyper-triton...

Global and collective dynamics
Oral Presentation
The hyperon-nucleon(Y-N) interaction is of great physical interest because it introduces a new quantum number strangeness in nuclear matter. It is predicted to be the decisive interaction in some high-density matter systems, such as neutron stars [1]. RHIC, the Relativistic Heavy Ion Collider, provides an ideal laboratory to study Y-N interaction because hyperons and nucleons are abundantly...
