Ariadne

Ariadne is a [Monte Carlo] [parton shower] [generator]. It was the first parton shower program that formulated [parton splitting] not in terms of partons (except for the splitting of a gluon to a quark-antiquark pair), but in terms of colour dipoles, each connecting a quark-antiquark pair. As such, it is the original [dipole shower].

The Ariadne project in a wider sense also includes the [Dipsy] Monte Carlo, as well as the [rope hadronisation] model for describing hadron formation in environments where there is a high colour charge density (such as a [heavy ion collision]).
