MPI@LHC 2010: 2nd International Workshop on Multiple Partonic Interactions at the LHC

29 Nov 2010, 08:00 → 3 Dec 2010, 18:00 GB

Glasgow, Scotland

Arthur Moraes (University of Glasgow)

Welcome to the second International Workshop on Multiple Partonic Interactions at the LHC "2nd MPI@LHC".

The aim of this workshop on Multiple Partonic Interactions (MPI) at the LHC is to raise the profile of MPI studies, summarizing the legacy from the older phenomenology at hadronic colliders and favouring further specific contacts between the theory and experimental communities.

The MPI are experiencing a growing popularity and are currently widely invoked to account for observations that would not be explained otherwise: the activity of the Underlying Event, the cross sections for multiple heavy flavour production, the survival probability of large rapidity gaps in hard diffraction, etc. At the same time, the implementation of the MPI effects in the Monte Carlo models is quickly proceeding through an increasing level of sophistication and complexity that in perspective achieves deep general implications for the LHC physics. The ultimate ambition of this workshop is to promote the MPI as unification concept between seemingly heterogeneous research lines and to profit of the complete experimental picture in order to constrain their implementation in the models, evaluating the spin offs on the LHC physics program.
