This paper reports the observation of Koba–Neilsen–Olesen-type scaling in the multiplicity distribution of medium-energy protons emitted in relativistic heavy-ion interactions and antiproton [Formula: see text] annihilations in nuclei. The data have been taken from 12C–AgBr (emulsion) interactions at 4.5 GeV∙c−1∙nucleon−1 and [Formula: see text] annihilation in emulsions at 1.4 GeV∙c−1

Multiplicity Distributions

The experimental results of multiplicity distributions of grey and relativistic shower particles emitted in the interactions of 28 Si and 12 C ions at 4.5 A GeV /c with nuclear emulsion are reported. The study of the multiplicity distributions of relativistic shower particles and medium energy target-associated protons produced in heavy-ion collisions seems to observe the semi-inclusive KNO scaling. A simplified universal function has been used to represent the experimental data.

Flavour Physics

In this proceedings, I present selected experimental results on heavy-flavour production at RHIC and at the LHC, which were presented at the Strangeness in Quark Matter 2017 conference. I will present a brief introduction to the heavy-flavour physics in heavy ion collisions and I will focus on recents measurements of in-medium energy loss and and collective properties of heavy-flavour particles, which provided important information on the mechanisms of heavy flavour interaction with the hot and dense medium created in ultra-relativistic heavy-ion collisions.
