  The spectra of lepton pairs from correlated open charm and bottom decays in
ultrarelativistic heavy-ion collisions are calculated. Our approach includes
energy loss effects of heavy quarks in deconfined matter which are determined
by temperature and density of the expanding parton medium. We find a noticeable
suppression of the initial transverse momentum spectrum of heavy quarks due to
the energy loss at LHC conditions. Within the central rapidity covered by the
ALICE detector system, the dominant contribution from bottom decays to the high
invariant mass dielectron spectrum is predicted.
