Open heavy-flavour production and elliptic flow in p-Pb collisions at the LHC with ALICE

Abstract

Measurements of open heavy flavour production in p–A collisions allow the investigation of Cold Nuclear Matter effects. In addition, they are an important tool for a complementary investigation of the long-range correlations found in small systems in the light flavour sector. In this work, production measurements of D mesons at mid-rapidity in p–Pb collisions at are reported. Production yields are also reported for the heavy-flavour hadron decay electrons at central rapidity at and 8.16 TeV. The elliptic flow (v2) of heavy-flavour hadron decay electrons in high-multiplicity p-Pb collisions at is found to be positive with a significance larger than 5σ.
