Workshop on Photon Physics and Simulation at Hadron Colliders

présidé par Matteo Cacciari (LPTHE - Paris), Nicolas Chanon (ETH - Zurich), Marco Delmastro (CERN), Bertrand Laforge (LPNHE - Paris), Giovanni Marchiori (LPNHE - Paris), Lydia Roos (LPNHE - Paris)
vendredi 30 mars 2012 de à (Europe/Paris)
Description A one-day workshop on prompt photon production at hadron colliders will be held at the beginning of 2012 in Paris, inside the campus of Université Pierre et Marie Curie.
The workshop will focus on the tools used to obtain the NLO theoretical predictions and the experimental problematics connected with the prompt photon cross section measurements.
In particular, the following items of discussions are envisaged:
  • survey of properties and characteristics of NLO prompt photon generators on the market
  • treatment of photon production (including fragmentation) and isolation in LO and NLO generators
  • experimental isolation prescription and connection with the theoretical predictions
The workshop is organised with the financial support of LPNHE and FRIF.
