Abstract

Measurements of quarkonia (heavy quark and antiquark bound states) and open-heavy flavour hadrons in hadronic collisions provide a unique testing ground for understanding quantum chromodynamics (QCD). Although recently there was significant progress, our understanding of hadronic collisions has been challenged by the observation of intriguing effects in high-multiplicity proton-proton (pp) and p-Pb collisions, such as collective phenomena. The excellent particle identification, track and decay-vertex reconstruction capabilities of the ALICE experiment are exploited to measure quarkonia as well as open-heavy flavour hadron production at midrapidity while quarkonium measurements are inclusive at forward rapidity. In this contribution, the first measurements of the elliptic flow (v2v_2) of J/ψJ/\psi in high multiplicity pp collisions is shown. New measurements of quarkonium and open-beauty hadron production in pp and p-Pb collisions are presented, such as the first measurement of the non-prompt D+\text{D}^{*+} polarization in pp collisions at s=13\sqrt{s}=13 TeV. The comparison of results with available models is also discussed.
