Feasibility of open charm elliptic flow measurement in CBM — •Selim Seddiki1,2 and Fouad Rami21Institut für Kernphysik, Goethe Universität, Frankfurt am Main — 2Institut Pluridisciplinaire Hubert Curien, Strasbourg, France

The Compressed Baryonic Matter experiment (CBM) planned at the Facility for Anti-proton and Ion Research (FAIR) accelerator, aims at studying the high net baryonic density region of the nuclear phase diagram by means of relativistic heavy ion collisions. Open charm particles are considered as one of the main observables, as they constitute penetrating probes of the early, dense phase of the collision. The elliptic flow of open charm is of particular interest, as it is expected to be sensitive to the creation and degree of thermalization of a potential partonic medium produced in the collision.

The measurement of open charm is an experimental challenge at FAIR energies, which are near the charm production threshold. We will present and discuss a feasibility study of the measurement of open charm and its elliptic flow with CBM. It has been found that the measurement of the integrated elliptic flow of open charm may be feasible within one year (∼ 1012 minimum bias collisions), with the actual conceptual set-up.
