Jet substructure in ATLAS at the LHC – a tool for discoveries and measurements
by
The ATLAS experiment at the Large Hadron Collider (LHC) applies jet substructure analysis techniques to extract the internal energy flow in high energy jets produced in the proton-proton collisions in searches for new physics as well as in Standard Model (SM) measurements. In this talk we will introduce the most commonly applied techniques and present an overview of results from the respective performance evaluations. In addition, we will discuss selected configurations of tagging algorithms designed to extract two- or three-prong energy flow patterns inside a jet, as generated by decays of SM particles like the W-boson or the top quark, or possible new heavy particles indicating physics beyond the SM. A brief presentation of recent results from searches and SM measurements, including the recent measurement of the internal structure of light quark and gluon jets, concludes the talk
