Abstract: (Springer)

The production of non-prompt D

^{0}

mesons from beauty-hadron decays was measured at midrapidity (|y| < 0.5) in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of

\sqrt{{\textrm{s}}_{\textrm{NN}}}

= 5.02 TeV with the ALICE experiment at the LHC. Their nuclear modification factor (R

_{AA}

), measured for the first time down to p

_{T}

= 1 GeV/c in the 0–10% and 30–50% centrality classes, indicates a significant suppression, up to a factor of about three, for p

_{T}

> 5 GeV/c in the 0–10% central Pb-Pb collisions. The data are described by models that include both collisional and radiative processes in the calculation of beauty-quark energy loss in the quark-gluon plasma, and quark recombination in addition to fragmentation as a hadronisation mechanism. The ratio of the non-prompt to prompt D

^{0}

-meson R

_{AA}

is larger than unity for p

_{T}

> 4 GeV/c in the 0–10% central Pb-Pb collisions, as predicted by models in which beauty quarks lose less energy than charm quarks in the quark-gluon plasma because of their larger mass.[graphic not available: see fulltext]
