"Open charm production in the nucleus-nucleus collisions"@en . "The submitted project is aimed to search for 3- and 4- body hadronic decays of charmed mesons (D and D_s) produced in Pb-Au collisions at 158 A GeV. Direct open charm production in nucleus-nucleus collisions is one of the fundamental processes studied upto now with the aim to establish the existence of the new state of strongly interacting matter, the Quark Gluon Plasma (QGP). Direct measurement of open charm production can also verify theoretical models for charmonium (J/psi) suppression in heavy ioncollisions, which in the case of the QGP formation should set in. Since 1993 our group is a member of the ultra-relativistic heavy ion experiments (at first the WA98 experiment and then, since 1997, the NA45/CERES experiment). In these experiments,formation of very hot and dense matter was achieved and some very convincing, though indirect, evidence about the existence of QGP was found. Our participation in the mentioned experiments was oriented from the beginning on exploitation of Silicon Drift"@en .
