An Analysis Framework for the modern HEP — •Raphael Friese, Thomas Müller, Roger Wolf, Joram Berger, Dominik Haitz, Fred Stober, Thomas Hauth, and Günter Quast — Institut für experimentelle Kernphysik, KIT

The analysis of data in high energy physics experiments is characterized by a number of iterations, during which the knowledge and assessment of the physics objects, under study, increase incrementally. Especially in a distributed environment, as for the LHC experiments this can be challenging. Analyses can significantly benefit from a carefully designed analysis software framework. The talk outlines the concepts of such a software framework, used on top of the analysis and reconstruction software CMSSW, of the CMS experiment. This framework is used by the KIT physics analysis groups. Data formats, the envisaged workflows and the advantages in terms of flexibility, reliability and turnaround time will be discussed. The framework is foreseen to serve a large variety of analyses in the areas of jet calibration, QCD multijets measurements, Higgs measurements and SUSY/BSM searches.
