ATHENA Jets, Heavy Flavor, Electroweak, and Beyond-the-Standard Model Working Group

Co-Conveners: Miguel Arratia (UC Riverside), Brian Page (BNL), Stephen Sekula (SMU), and Ernst Sichtermann (LBNL)

The Jets, HF, EW, and BSM Group is investigating a number of channels and signatures that should benefit from the proposed design configuration(s) of the ATHENA detector. Below, we outline the various physics areas that might be of value to the detector proposal. Below that we provide information about different specific signatures/efforts within the group.

Current Physics Results

Charm-Jet Tagging

Results in this effort (to identify and categorize jets based on track and/or neutral information in the jet) are presently available from fast simulation (Delphes) informed in part by full simulation (DD4HEP). A note documenting work conducted during Summer 2021 is available below.
