    "abstract": "The production of particles with double, triple and hidden charm in heavy ion\ncollisions is studied in the framework of the statistical coalescence model.\nAccording to the postulates of the model, the charm quark-antiquark pairs are\ncreated at the initial stage of a heavy ion reaction in hard parton collisions.\nThe amount of charm is assumed to be unchanged at later stages. The charm\n(anti)quarks are distributed among different hadron species at hadronization\naccording to the laws of statistical physics. Several approaches to the\nstatistical treatment of charm hadronization are considered. The grand\ncanonical approach is appropriate for systems containing large number of charm\n(anti)quarks. The exact charm conservation and Poissonian fluctuations of the\nnumber of charm quark-antiquark pairs should be taken into account, if the\naverage number of these pairs is of oder of unity or smaller. The charm\nhadronization in a subsystem of a larger system is discussed. It is explained\nwhy the canonical approach is not appropriate for the description of charm\nhadronization. The obtained formulas can be used to calculate the production of\ncharm in heavy ion collisions in a wide energy range.",
