Open charm enhancement by secondary interactions in relativistic nucleus-nucleus collisions?

W. Cassing, L. A. Kondratyuk, G. I. Lykasov +1

We calculate open charm production in $Pb+Pb$ reactions at SPS energies within the HSD transport approach - which is based on string, quark, diquark ($q, \bar{q}, qq, \bar{q}\bar{q…
