Looking inside jets - jet substructure techniques and their application in ATLAS — •Chris Malena Delitzsch — University of Arizona, Tucson, USA

The unprecedented center-of-mass energy of the proton-proton collisions at the Large Hadron Collider enables the production of hadronically decaying particles such as W/Z/H bosons and top quarks with a transverse momentum much larger than their rest mass, resulting in the collimation of their decay products. To enhance the sensitivity to new physics and the precision of Standard Model measurements at high transverse momenta, many different jet substructure techniques have been developed and established over the past years that take advantage of the different radiation patterns within the jet depending on the initiating particle. This talk describes the state of the art substructure and tagging techniques and their applications in physics analyses in ATLAS and highlights the challenges of the jet substructure field.
