Abstract
I discuss the elliptic flows of with different production mechanisms in TeV Pb-Pb collisions. If the final are mainly from the recombination of uncorrelated charm and anticharm quarks at , charm and anticharm quarks will carry large collective flows of the bulk medium, which will be inherited by the regenerated . This indicates a larger elliptic flow of than that of which can be regenerated at , . However, if the final are mainly from the transitions of caused by the color screening of quark-gluon plasma its elliptic flow should be close to the elliptic flow of , . Therefore, elliptic flow is a sensitive probe for its production mechanisms in relativistic heavy ion collisions.
