PHENIX has measured the $b\overline{b}$ production cross section in $p$$+$$p$ collisions at $\sqrt{s} = 500$~GeV. In the absence of displaced-vertex $b$-tagging, this is made possible by exploiting the properties of $B^{0}-\overline{B^{0}}$ oscillations. Like-sign muon pairs in the PHENIX muon arms are measured in order to extract this signal. We report the $b\overline{b}$ differential...

The ALICE experiment's heavy-ion programme allows us to study the hot, high energy-density state of matter formed in ultrarelativistic nuclear collisions. In particular, heavy quarks (charm and beauty) serve as calibrated probes of the medium, since they are predominantly produced during the initial hard scatterings in the collision. ALICE's excellent tracking, vertexing and particle...

The study of heavy-quark production (charm and beauty) in pp collisions at LHC energies allows us to test perturbative QCD calculations and provides a reference for studies in heavy-ion collisions. Measurements in p--Pb collisions help to characterize the effects due to the presence of a nucleus in the collision (cold nuclear matter effects). ALICE has provided measurements of the nuclear...

Predictions obtained with the up-to-date version of our POWLANG transport code for heavy-flavour production in high-energy nuclear (A-A and now also p-A) collisions will be presented. To the usual Langevin evolution in the plasma we added a new modeling of the hadronization stage including the recombination with thermal partons from the medium at the decoupling hypersurface, to form...
