Charm estimate from the dilepton spectra in nuclear collisions
The validity of a recent estimate of an upper limit of charm production in central Pb+Pb collisions at 158 A GeV is critically discussed. Within a simple model we study properties of the background subtraction procedure used for an extraction of the charm signal from the analysis of dilepton spectra...
