ATOM/Fastlim: Recasting LHC constraints on new physics models

Presented by Dr. Kazuki SAKURAI on 21 Jul 2014 from 14:50 to 15:10
Type: Alternative Theories
Track: Alternative Theories


The results of ATLAS and CMS beyond the Standard Model searches are very useful to constrain various new physics modes, yet they are originally designed to search for a particular model. Recasting existing analyses on to an arbitrary model involves various subtleties and one has to simulate detector responses and selection cuts as realistic as possible. For this task, we developed two programs: ATOM (Automated Testing Of Models) and Fastlim. ATOM takes event files as inputs and calculates the efficiencies of various analyses automatically, which can be used to calculate an exclusion p-value for an given model. Fastlim, on the other hand, takes spectrum files as inputs and immediately calculates an exclusion p-value using pre-calculated efficiencies of various simplified topologies. In this talk, we discuss the methodology used and present performances of these tools.
