Query: Measurement of electrons from charm and beauty hadron decays in p-Pb
  collisions at $\sqrt{s_{\mathrm{NN}}} = 8.16\,$TeV with ALICE   Lattice Quantum Chromodynamics (QCD) calculation predicts that a
colour-deconfined QCD matter, Quark-Gluon Plasma (QGP), is formed at high
temperature and energy density reached in ultra-relativistic heavy-ion
collisions. Heavy quarks (charm and beauty) are mostly produced by initial hard
scatterings before the formation of the QGP. Therefore heavy-flavour hadrons
are ideal probes to investigate the properties of the hot and dense QCD matter.
In Pb-Pb collisions, a strong suppression of the production of heavy-flavour
hadrons with high transverse momentum has been observed. A deeper understanding
of heavy-flavour production and interaction with the QGP requires detailed
studies of Cold Nuclear Matter (CNM) effects in order to clarify the role of
initial- and final-state effects on their production. CNM effects include
shadowing and/or saturation of partons, energy loss in CNM and
$k_{\rm{T}}$-broadening. Such effects on heavy quark production can be studied
in proton-nucleus collisions via heavy-flavour decays electrons.
High-$p_{\rm{T}}$ electrons are especially interesting because they mainly
originate from beauty hadrons. We report the $p_{\rm{T}}$ dependence of the
nuclear modification factor ($R_{\rm{pPb}}$) and ratio of cross section of
heavy-flavour decays electrons in p-Pb collisions with different collision
energies, $\sqrt{s_{\mathrm{NN}}} = 8.16\,$TeV and $\sqrt{s_{\mathrm{NN}}} =
5.02\,$TeV.
