  Summary of NA61/SHINE results on the Onset of Fireball 15m
  
  The NA61/SHINE, a multipurpose fixed-target facility at the CERN SPS, carry on the research on the onset of deconfinement and search of the critical point studying the hadron production properties in nucleus-nucleus, proton-proton and proton-nucleus interactions as a function of collision energy and mass of the colliding nuclei. The latest results from the NA61/SHINE systematic scan revealed surprising behaviour of several hadron production properties as function of mass of colliding nuclei, suggesting a new threshold behaviour in heavy-ion physics - the Onset of Fireball. A brief report will summarize the NA61/SHINE results in the context of the new phenomenon and give an edge on the following interpretation by professor Edward Shuryak.

  Formation of fireball and clustering near the (hypothetical) critical point 1h
  
  In this talk I want to discuss two separate topics. One is the mechanism of fireball formation, as a function of centrality, or the atomic numbers of the collided nuclei. The central idea is that, a rather weak attraction between QCD flux tubes can lead to fireball formation when their number gets above a certain critical value, see 1503.04759 and 1404.1888. The second topic is about multinucleon clustering at freezeout, and role of multinucleon forces close to the critical point, from 2010.02785.
