Abstract :
Activity in tuning of Monte Carlo event generator models to experimental data has been revitalised by the approach and arrival of data in a new energy regime, from the Large Hadron Collider experiments. The state of the art in MC tuning technology is the Professor toolkit, which is fundamentally based on bin-wise parameterisation of computationally intensive MC observables as a function of generator parameters: the parameterisation then acts as a CPU-efficient model of the generator, making tuning amenable to numerical minimisation. In this talk I summarise the Professor method and some of the tuning results obtained in response to LHC data, with an outlook upon the potential of the MC parameterisation method for improved estimation of uncertainties in MC tunes and predictions.
