The Angantyr model for heavy ions in Pythia8

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskriftPeer review


Pythia8 is the only general purpose event generator able to produce complete fully exclusive hadronic final states in collisions involving heavy ions. The model that allows this is called Angantyr and will be discussed in this contribution. The contribution also discusses models based on interactions between strings in an extention of the Lund model that are able to describe some collective effects in proton–proton collisions. In particular, a reformulation of the so-called shoving will be described, which also works for heavy ion collisions as generated by the Angantyr model. Preliminary results for the ridge effects are presented for proton–proton and proton–lead collisions.
