Heavy-flavour azimuthal correlations in $pp$ and $p$-Pb collisions with ALICE

Azimuthal correlation studies of heavy-flavour particles with chargedparticles inppcollisions are powerful tools to characterize the charm fragmentationprocess. Comparisons of $pp$ and $p-$P$b$ measurements of heavy quarks hadronizationproducts allow us to investigate how cold nuclear matter effects could affect theheavy-quark hadronization process. We present ALICE measurements of azimuthalcorrelations of prompt $D$-mesons with charged hadrons in $pp$ collisions at $√s=7TeV$ and $p-$Pb collisions at $\sqrt{SNN} = 5.02 TeV$.
