The D meson production at forward rapidities in d+Au processes is calculated using
a pQCD based model, assuming that this treatment could be used as a baseline for
distinct dynamical and medium effects. It is analysed ...

We study, in a hydrodynamical approach, the energy dependence of the kaon mT spectra in central Pb+Pb (Au+Au) collisions. We show that the experimental data of the inverse slope parameter can be reproduced with a reasonable ...
