DRoplet and hAdron Generator for Nuclear Collisions: an update

The Monte Carlo generator DRAGON simulates hadron production in ultrarelativistic nuclear collisions. The underlying theoretical description is provided by the blast-wave model. DRAGON includes second-order angular anisotropy in transverse shape and the amplitude of the transverse expansion velocity. It also allows to simulate hadron production from a fragmented fireball, e.g. as resulting from spinodal decomposition happening at the first-order phase transition. The previous version of this program (AEDK_v1_0) may be found at dx.doi.org/10.1016/j.cpc.2009.02.019.
