Boosting jets in Run 2: highlights from Standard Model measurements and searches for new physics 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, a variety of jet substructure techniques have been developed in the last decade that take advantage of the different radiation patterns within the large-radius jet depending on the initiating particle. The usage of jet substructure techniques is however not just limited to the identification of the origin of jets but also allows for the precise measurement of jet properties to probe and constrain the Standard Model in extreme regions of phase space.
This talk describes the state of the art substructure and tagging techniques and discusses highlights from Standard Model measurements and searches for new physics in ATLAS using these versatile techniques.
