Description
Heavy quarks (charm and beauty) are predominantly produced via initial hard parton scatterings in the early stages of hadronic collisions. Thus, they are ideal probes
of the QCD matter since they lose energy by means of elastic scatterings and radiative
processes while propagating through the strongly-interacting medium created in
high-energy heavy-ion collisions. According to theoretical models, the parton energy
loss is colour charge and parton mass dependent. In particular, it is expected that
beauty quarks lose less energy than charm and light quarks. These dependencies can be
studied by comparing the nuclear modification factor of beauty jets with that of charm
or light-parton jets. The measurement of beauty-jet production in p-Pb collisions is
needed to quantify cold nuclear matter effects, a fundamental step for the
interpretation of Pb-Pb results.
In this poster we present Monte Carlo based performance studies of beauty-jet
tagging via displaced secondary vertex reconstruction, obtained with ALICE for p-Pb
collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV. The tagging technique, its
performance in terms of efficiency and beauty jet selection purity, and the
corrections required for measuring the cross section of beauty-jet production will
be described. Finally, prospects for measurements in LHC Run 2, will also be presented.
