Ariadne version 4

A program for simulation of QCD cascades implementing the colour dipole model

This is the official Home Page for the Ariadne program. Here you can always find the latest version of the program and up-to-date documentation. Release 4.10 the Ariadne distribution also included version 1.0 of the LDCMC program for generating initial state parton chains according to the Linked Dipole Chain model.

To run Ariadne, you also need to install the Pythia/Jetset programs. In addition you may need to install the LEPTO program. You also might like to look at some sample programs to get started with running Ariadne.

PLEASE NOTE: If results obtained by the Ariadne program are used in a publication, the reference should read something like:
L. Lönnblad, Ariadne version 4.12 program and manual, Comput. Phys. Commun. 71 (1992) 15.
If, in addition, the LDCMC program was used, the reference should read something like:
H. Kharraziha, L. Lönnblad, LDCMC version 1.0 program and manual, Comput. Phys. Commun. 123 (1999) 153.

Sample programs for running Ariadne

Ariadne is a subroutine package, and to use it you need to supply a main program calling Ariadne subroutines. Here are some samples.

  • Generating Z0 -> hadrons at LEP: jtest.f
  • Generating ep DIS events at HERA (Requires that you also link the LEPTO program): ltest.f
  • Generating High-pt QCD events including fragmentation production of J/Psi at LHC: ptest.f
  • Generating ep DIS events at HERA with LDCMC/Ariadne. Here you need one C++ main program calling a Fortran steering subroutine (Requires that you also link the LEPTO program): test.ccldctest.f

All these programs need to be linked with both Pythia and Ariadne.
