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 √ sNN = 5.02 TeV are reported. Production yields are also reported for the heavy-flavour hadron decay electrons at central rapidity at √ sNN = 5.02 and 8.16 TeV. The elliptic flow (v2) of heavy-flavour hadron decay electrons in highmultiplicity p-Pb collisions at √ sNN = 5.02 TeV is found to be positive with a significance larger than 5σ.
