  Measurements in heavy-flavour azimuthal angular correlation provide insight
into the production, propagation, and hadronization of heavy-flavour jets in
ultra-relativistic hadronic and heavy-ion collisions. These measurements across
different particle species help to isolate the possible modification in
particle production and fragmentation due to different mass and quark contents.
Jet correlation studies give direct access to the initial parton dynamics
produced in these collisions. \\ This article studies the azimuthal angular
correlations of heavy-flavour hadrons (charm and beauty mesons and charm
baryons) in pp collisions at $\sqrt{s} =$ 7 TeV using PYTHIA8. We study the
production of heavy-flavour jets with different parton-level processes,
including multi-parton interactions and different color reconnection
prescriptions. The heavy-flavour hadrons correlations are calculated in the
different triggers and associated \pt intervals to characterize the impact of
hard and soft scattering. The yields and the widths associated with the
near-side (NS) and away-side (AS) correlation peaks are calculated and studied
as a function of associated \pt for different trigger \pt ranges.
