Transverse-momentum and event-shape dependence of D-meson flow harmonics in Pb–Pb collisions at sNN=5.02TeV

Charm and beauty isolation from heavy flavor decay electrons in p+p and Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV at LHC

“…Thus, in an alternative way, the beauty was commonly measured indirectly via its decay products, such as electrons, non-prompt D 0 and J∕ mesons. It was observed that the AA of its decay daughters are less suppressed compared to those of prompt open charm mesons, which is consistent with the mass hierarchy of the parton energy loss in the medium [14,15,16,17,18]. Recently, a sizable electron 2 from beauty decays was also measured by ALICE [19], which indicates strong interactions between beauty and the medium.…”

“…Recently, a sizable electron 2 from beauty decays was also measured by ALICE [19], which indicates strong interactions between beauty and the medium. Since charm looks no significant difference compared with light quarks in terms of AA and 2 in RHIC and LHC energies [5,18], it is crucial to study whether beauty is sensitive to the different medium created at RHIC and LHC energies and behaves differently under different temperatures.…”

Rapidity dependence of heavy-flavour production in heavy-ion collisions within a full 3+1 transport approach: quenching, elliptic and directed flow

“…This allows one to get access to the quenching of the distributions at high momentum due to in-medium parton energy-loss and to the collective (radial and elliptic) flow acquired by the heavy quarks in the expanding fireball. More recently HF studies have been extended to observables sensitive to event-by-event fluctuations of the initial geometry of the fireball, like the triangular flow v 3 [5][6][7] and the event-shape-engineering analysis of the D-meson v 2 [6,8], both satisfactorly reproduced by several transport calculations [9][10][11][12][13][14][15][16][17]. Another interesting development concerns the modification of HF hadrochemistry in nucleus-nucleus collisions (and, more generally, in high-multiplicity hadronic collisions), with a relative enhancement of the production of D s and B s mesons and Λ c baryons relative to non-strange mesons observed by the ALICE [18,19] and CMS [20,21] collaborations at the LHC and by the STAR [22][23][24] collaboration at RHIC.…”
