Description
Heavy-flavour production studies in pp collisions, besides providing the necessary baseline for measurements in Pb$-$Pb collisions, constitute a precision test of perturbative QCD calculations. In complex systems such as p$-$Pb collisions, it gives insights into the cold nuclear matter (CNM) effects and also characterizes the nuclear parton distribution functions in the low-$\it{x}$ region, where gluon saturation sets in. Furthermore, their production as a function of charged-particle multiplicity in pp and p$-$Pb collisions provides insights into the role of multiple-parton interactions (MPI) and the interplay between hard and soft mechanism in particle production. In p$-$Pb collisions, the production is also influenced by the concurrent multiple binary nucleon-nucleon collisions.
In this contribution, we will present the measurement of the yield of electrons from heavy-flavor hadron decays at mid-rapidity ($\left|\eta\right|<$ 0.8) as a function of the transverse momentum and charged-particle multiplicity estimated at mid-rapidity ($\left|\eta\right|<$ 1) in pp collisions at ${\sqrt{s}}$ = 13 TeV and in p$-$Pb collisions at ${\sqrt{s_{\rm NN}}}$ = 8.16 TeV.
