We review in this contribution the information we can obtain from heavy-ion experiments about the interaction of mesons with matter. We demonstrate that the vector mesons seen in experiments come predominantly from low densities. Kaons offer a better opportunity but most of the presently available experimental observables do not allow to analyze separately the three essential unknown quantities: the kaon production cross-section in the medium, the K+N potential interaction at finite densities and temperatures and the kaon (elastic or charge exchange) rescattering cross-section in the medium. We propose a measurement which almost exclusively tests the K+N potential.

The Large Hadron Collider at CERN allows us to study heavy-ion collisions at an un- precedented energy. ALICE, A Large Ion Collider Experiment, is the experiment ded- icated to the investigation of heavy-ion collisions. In this contribution, recent open heavy-flavour results from pp collisions at [Formula: see text]= 5.02, 7, 8 and 13 TeV and p–Pb collisions at [Formula: see text] = 5.02 TeV, collected with the ALICE detector during the LHC Run-1 and Run-2 are presented. The results include the production cross section, nuclear modification factor and multiplicity dependence studies of production of D mesons and electrons from heavy-flavour hadron decays at mid-rapidity and of muons from heavy-flavour hadron decays at forward rapidity. Charm production was measured down to [Formula: see text] = 0 GeV/[Formula: see text] in pp and p–Pb collisions. Recent measurements of the production cross section of heavy charmed baryons such as [Formula: see text] (in pp and p–Pb) and [Formula: see text] (in pp) are discussed. The results are compared with theoretical model predictions.

Measurements have been made of the relative X-ray .production cross-section ratios L./Ly, L./Lp and L./Ll using electrons of energy from 20 to 100 keV incident on thin targets of tin and gadolinium. The experimental ratios obtained are compared with theoretical values. Modification of these ratios due to the formation of double-vacancy atomic states has been calculated, but this effect on its own is not sufficient to account for the discrepancy between the L./Ll theoretical and experimental results for tin.
