18. Measurements of Upsilon production in p+p collisions at sqrt(s)=500 GeV with the STAR experiment

Mr Leszek Kosarzewski (Warsaw University of Technology)

Studies of the production cross-sections for various $\Upsilon$ states have provided valuable constraints on the bottomonium production models. Recently, a more differential measurement, namely the relative production yields as a function of event multiplicity, has been presented for the $\Upsilon$ mesons in p+p collisions at the LHC. A stronger-than-linear rise is observed, indicating an...

21. On strangeness from NA61/SHINE

Mr Maciej Piotr Lewicki (University of Wroclaw (PL))

NA61/SHINE is a fixed target experiment at the CERN Super-Proton-Synchrotron. The main goals of the experiment are to discover the critical point of strongly interacting matter and to study the properties of the onset of deconfinement. In order to reach these goals, a study of hadron production properties is performed in nucleus-nucleus, proton-proton and proton-nucleus interactions as a...

9. Centrality dependence of freeze-out temperature fluctuations in Pb-Pb collisions at the LHC

Dariusz Prorok (Institute of Theoretical Physics University of Wroclaw)

Many data in the High Energy Physics are, in fact, sample
means. It is shown that when this exact meaning of the
data is taken into account and the most weakly bound
states are removed from the hadron resonance gas, the
whole spectra of pions, kaons and protons measured at
midrapidity in Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$
TeV can be fitted simultaneously. The invariant...
