Workshop on Multi-Parton Interactions at the LHC

The workshop on multi-parton interactions and multi-parton pdfs will take place in DESY Hamburg on September 13-15, 2010.

Multiple parton interactions (MPI) are one of the most common, yet poorly understood, phenomena at the LHC. The modelling implemented in Monte Carlo generators aims to describe multiple scattering throughout the whole range of scales, from soft to hard. At the same time, much work is going on to improve theoretical understanding of multiple scatterings at both low and high pt, and study the related phenomenology at the LHC. Therefore it is extremely important to combine theoretical and experimental efforts in order to achieve a better description of multiple interactions, and, in general, the underlying event.

Topics to be discussed include:

  • improving theoretical understanding of MPI,
  • implementation in general purpose MC programs,
  • current development of double parton distribution functions and use of them in MC programs,
  • MPI contributions to signal and background processes,
  • recent experimental results from the LHC and the Tevatron,
  • plans for future measurements of MPI at the LHC,
  • continued development of better MC event generators.
