Monte Carlo Tuning with ATLAS Data

The ATLAS experiment has published a number of measurements which are sensitive to the modelling of non-perturbative effects in event generators. These measurements together with existing measurements from other colliders have been used to tune the parameters of such models. This talk presents how this optimisation was performed within ATLAS using the "Rivet" and "Professor" software packages. The optimised parameters and comparisons of the corresponding Monte Carlo predictions to data are displayed.
