Charm elliptic flow from quark coalescence dynamics
نویسنده
چکیده
From covariant transport theory, a significant ∼ 10% light quark elliptic flow at RHIC implies an elliptic flow of similar magnitude for charm quarks, at moderately large pT > 2.5 − 3 GeV. At lower transverse momenta, charm quark elliptic flow reduces progressively, reminiscent of the mass ordering pattern in ideal hydrodynamics. From the quark flows we predict the elliptic flow of D mesons at RHIC via quark coalescence. The large parton opacities needed to generate the light quark flow also lead to substantial ∼ 40 − 50% secondary charm production. PACS numbers: 12.38.Mh; 24.85.+p; 25.75.Gz; 25.75.-q

Hadronization via Coalescence
We review the quark coalescence model for hadronization in rel-ativistic heavy ion collisions and show how it can explain the observed large baryon to meson ratio at intermediate transverse momentum and scaling of the elliptic flows of identified hadrons. We also show its predictions on higher-order anisotropic flows and discuss how quark coalescence applied to open-and hidden-charm mesons can ...
متن کاملInsight from elliptic flow of open charm mesons using quark coalescence model at RHIC and LHC energies
A study of elliptic flow of open charm mesons, D and D S using quark coalescence as a mechanism of hadronization within the framework of a multi-phase transport model has been presented. We have studied the transverse momentum dependence of the elliptic flow parameter at mid-rapidity (|y| < 1.0) for minimum bias Au+Au collisions at √ sNN = 200 GeV (RHIC) and Pb+Pb collisions √ sNN = 2.76 TeV (L...
متن کاملElliptic flow and nuclear modification factors of D-mesons at FAIR in a Hybrid-Langevin approach
The Compressed Baryonic Matter (CBM) experiment at the Facility for Anti-proton and Ion Research (FAIR) will provide new possibilities for charm-quark (D-meson) observables in heavy-ion collisions at low collision energies and high baryon densities. To predict the collective flow and nuclear modification factors of charm quarks in this environment, we apply a Langevin approach for the transport...
متن کاملThermalization of Heavy Quarks in the QGP
Recent experimental results on the transverse-momentum spectra (pT spectra) and the elliptic flow, v2, of non-photonic single electrons [K +04, L+04], whose main source at pT & 2GeV/c is the semileptonic decay of open-charm (and bottom) mesons, indicate that D mesons may have about the same v2 as light mesons. Calculations within a quark-coalescence model [GKR04] show that this can be explained...
متن کاملResonance recombination model and quark distribution functions in the quark-gluon plasma
We investigate the consequences of space-momentum correlations in quark phase-space distributions for coalescence processes at the hadronization transition. Thus far it has been proved difficult to reconcile such correlations with the empirically observed constituent quark number scaling (CQNS) at the Relativistic Heavy Ion Collider (RHIC). To address this problem we combine our earlier develop...
