Study of Open Heavy-Flavour Hadron Production in Pp and P–pb Collisions with ALICE

Measurement of heavy-flavour production in small systems can be used to test the Quantum ChromoDynamic (QCD) models. In this manuscript, the production cross section of D mesons at midrapidity and open heavy-flavour decay muons (HFM) measured at forward rapidity in pp collisions at \(\sqrt{s}\) \(=\) 5.02 TeV, and open heavy-flavour decay electrons (HFE) measured at midrapidity in pp collisions at \(\sqrt{s}\) \(=\) 13 TeV with ALICE detector will be presented. The self-normalized yield of open heavy-flavour decay electrons and muons as a function of multiplicity in pp and p–Pb collisions will be presented. Finally, the latest result on nuclear modification factor (\(Q_{{\mathrm{pPb}}}\)) of D mesons and the \(\nu _{2}\) of open heavy-flavour decay electrons and muons in p–Pb collisions will be discussed.
