BAT SUSY 2011

In 2011 we’ll try to focus our analysis work within the multi-lepton, i.e. more than two, group. The 2010 analysis is signed by 14 people. The strategy is to have a complete analysis chain in Bern which we all work on. Then studies are taken by individuals and effects always evaluated by the full chain. WE SHOULD SIGN UP FOR 4 SUCH TASKS, I would say. One for each phd.
