Theory
Hadron spectra measured in high-energy collisions present distributions which can be derived from the non-extensive statistical and thermodynamical phenomena [1,2]. Based on earlier theoretical developments, it seems, the methods are very applicable for jets hadronization processes in electron-positron, proton-proton, and even in heavy-ion collisions [3,4]. Here in this talk, I would like to...

Baryons and strangeness
Experimental
The ALICE detector at LHC allows to study Pb--Pb collisions at the new energy frontier. At this energy almost equal amounts of matter and antimatter are produced in the central rapidity region. Closely related to this is the production of (hyper)nuclei and anti-(hyper)nuclei, which are measured with nearly similar abundances. Based on its high tracking and particle identification capabilities,...

Baryons and strangeness
Experimental
In ultrarelativistic heavy-ion collisions with high particle multiplicities, a muon can be bound to a charged hadron by Coulomb force and form a hydrogen-like atom. Among these atoms, the antimatter muonic hydrogen ($\bar{p}-\mu$) and the $K-\mu$ atom have been predicted but not yet been discovered[1]. At the STAR experiment, muon identification at low transverse momentum provides a great...

Baryons and strangeness
Experimental
Hadronic resonances serve as unique probes in the study of the hot and dense nuclear matter produced in heavy-ion collisions. The properties of the hadronic phase of the collision (the temperature and lifetime) can be extracted from measurements of the suppression of resonance yields with respect to the yields of stable particles. A comparison of the transverse-momentum spectra of the...

Experimental
Transverse momentum spectra and yields of charged $\Xi$ and $\Omega$ at mid-rapidity in proton-proton (pp), proton-lead (p-Pb) and lead-lead (Pb-Pb) collisions measured in the ALICE experiment at LHC will be presented. These particles are reconstructed via their cascade weak decay topology into charged particles only, using the excellent tracking and particle identification capabilities of the...

Experimental
Bottomonia are important probes of the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. The three Y states (1S, 2S, 3S) were measured separately using the Compact Muon Solenoid (CMS) experimental apparatus and observed to disappear sequentially in PbPb collisions at 2.76 TeV. However, recent measurements in pp and pPb...

The $J/\psi$ production mechanism in elementary particle collisions is not yet exactly known.
For many years measurements of the J/$\psi$ cross-section have been used to test different J/$\psi$ production models. While many models can describe relatively well the experimental data on the J/$\psi$ cross-section in $p+p$ collisions, they have...
