Universal strangeness production and size fluctuactions in small and large systems
/ Castorina, P. (Catania U. ; INFN, Catania) ; Floris, M. (CERN) ; Plumari, S. (Catania U. ; INFN, LNS) ; Satz, H. (Bielefeld U.)
Strangeness production in high multiplicity events gives indications on the transverse size fluctuactions in nucleus-nucleus ($AA$), proton-nucleus ($pA$) and proton-proton ($pp$) collisions. In particular the behavior of strange particle hadronization in "small" ($pp,pA$) and "large" ($AA$) initial configurations of the collision can be tested for the specific particle species, for different centralities and for large fluctuations of the transverse size in $pA$ and $pp$ by using the recent ALICE data.

Heavy-flavour and quarkonium production in the LHC era: from proton-proton to heavy-ion collisions
/ Andronic, A. (Darmstadt, EMMI) ; Arleo, F. (Ecole Polytechnique ; Annecy, LAPTH) ; Arnaldi, R. (INFN, Turin) ; Beraudo, A. (INFN, Turin) ; Bruna, E. (INFN, Turin) ; Caffarri, D. (CERN) ; Conesa del Valle, Z. (Orsay, IPN) ; Contreras, J.G. (Prague, Tech. U.) ; Dahms, T. (Munich, Tech. U., Universe) ; Dainese, A. (INFN, Padua) et al.
This report reviews the study of open heavy-flavour and quarkonium production in high-energy hadronic collisions, as tools to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure at high energy to deconfinement and the properties of the Quark-Gluon Plasma. Emphasis is given to the lessons learnt from LHC Run 1 results, which are reviewed in a global picture with the results from SPS and RHIC at lower energies, as well as to the questions to be addressed in the future.

Hawking-Unruh Hadronization and Strangeness Production in High Energy Collisions
/ Castorina, P. (Catania U. ; INFN, Catania ; CERN ; Bielefeld U.) ; Satz, H. (Bielefeld U.)
The thermal multihadron production observed in different high energy collisions poses many basic problems: why do even elementary, $e^+e^-$ and hadron-hadron, collisions show thermal behaviour? Why is there in such interactions a suppression of strange particle production? Why does the strangeness suppression almost disappear in relativistic heavy ion collisions? Why in these collisions is the thermalization time less than $\simeq 0.5$ fm/c? We show that the recently proposed mechanism of thermal hadron production through Hawking-Unruh radiation can naturally answer the previous questions. Indeed, the interpretation of quark- antiquark pairs production, by the sequential string breaking, as tunneling through the event horizon of colour confinement leads to thermal behavior with a universal temperature, $T \simeq 170$ Mev,related to the quark acceleration, a, by $T=a/2\pi$.

Quarkonium production in high energy proton-proton and proton-nucleus collisions
/ Conesa del Valle, Z. (Strasbourg, IPHC ; CERN) ; Corcella, G. (Frascati) ; Fleuret, F. (Ecole Polytechnique) ; Ferreiro, E.G. (Santiago de Compostela U., IGFAE) ; Kartvelishvili, V.

(Fermilab) et al.
We present a brief overview of the most relevant current issues related to quarkonium production in high energy proton-proton and proton-nucleus collisions along with some perspectives. After reviewing recent experimental and theoretical results on quarkonium production in pp and pA collisions, we discuss the emerging field of polarisation studies. [...]

Perspectives on heavy-quarkonium production at the LHC
/ Lansberg, J.P. (Heidelberg U.) ; Rakotozafindrabe, A. (IRFU, SPhN, Saclay) ; Artoisenet, P. (Louvain U., CP3) ; Blaschke, D. (Wroclaw U.) ; Cugnon, J. (Liege U.) ; d'Enterria, D. (CERN) ; Kraan, A.C. (INFN, Pisa) ; Maltoni, F. (Louvain U., CP3) ; Prorok, D. (Wroclaw U.) ; Satz, H. (Bielefeld U.)
We summarise the perspectives on heavy-quarkonium production at the LHC, both for proton-proton and heavy-ion runs, as emanating from the round table held at the HLPW 2008 Conference. The main topics are: present experimental and theoretical knowledge, experimental capabilities, open questions, recent theoretical advances and potentialities linked to some new observables..
