Figure Caption

The baryon-to-meson ratios in the light-flavour (Lambda/K0s) and charm (Lambdac/D0) sector measured in pp collisions at 13 TeV for similar low- and high-multiplicity classes at midrapidity. The ratio is compared to the light-flavour ratio measured by ALEPH in e+e- collisions at 91 GeV. The uncertainties of the ALEPH measurement are treated as uncorrelated, and the data for pT > 6 GeV/c is not shown due to large statistical uncertainties/fluctuations
