Boosted Hadronically Decaying Tops in New Physics Searches.

Michihisa Takeuchi
Top momentum reconstruction often plays an important role for new physics signal reconstruction at the LHC. In principle, it is possible to reconstruct hadronically decaying top momentum fully but suffering from large QCD and combinatorics background. Starting from geometrically large size of jets and looking into their substructure, we can efficiently reduce these background. We develop {\sc HEPTopTagger} by adopting combination of Cambridge/Aachen algorithm and mass drop criterion. For physics applications, we illustrate scalar top...
