Abstract

In this report, highlights on the multiplicity-dependent measurements of heavy-flavour hadrons performed by the ALICE experiment, are presented. The heavy-flavour baryon-to-meson Λc0/D0 and strange-to-non-strange D meson DS+/D0 ratios in different charged-particle multiplicity intervals are discussed. Recent measurements of heavy-flavour self-normalised yields as a function of the self-normalised charged-particle multiplicity in pp collisions at √S = 13 TeV are also reported. Measurement of jets containing heavy-flavour hadrons in pp and p–Pb collisions at √SNN = 5.02 TeV and the recent measurements of azimuthal correlations of heavy-flavour hadron decay electrons and charged hadrons in pp collisions at √S = 5.02 TeV are presented.

Highlights

Heavy quarks are produced through hard scattering processes of partons at the early stages of an ultra-relativistic heavy-ion collision. They act as sensitive probes for exploring the properties of the hot and dense deconfined matter formed in such collisions, known as the quark-gluon plasma (QGP) [1]
Heavy-flavour measurements in pp collisions are fundamental as reference measurements to investigate the properties of the QGP, since the latter is not expected to be formed in small systems, but are important since they provide precise tests for the perturbative QCD calculations
In ALICE [2], the open heavy-flavour hadron production is studied through their different decay channels in a wide rapidity range
