    "abstract": "We show that large fluctuations of D mesons kinetic energy (or momentum)\ndistributions might be a signature of a phase transition to the quark gluon\nplasma (QGP). In particular, a jump in the variance of the momenta or kinetic\nenergy, as a function of a control parameter (temperature or Fermi energy at\nfinite baryon densities) might be a signature for a first order phase\ntransition to the QGP. This behaviour is completely consistent with the order\nparameter defined for a system of interacting quarks at zero temperature and\nfinite baryon densities which shows a jump in correspondance to a first order\nphase transition to the QGP. The $J/\\Psi$ shows exactly the same behavior of\nthe order parameter and of the variance of the D mesons. We discuss\nimplications for relativistic heavy ion collisions within the framework of a\ntransport model and possible hints for experimental data.",
