SUMMARY:gFEX: A Level 1 Calorimeter Trigger for ATLAS at the Run3 LHC 
 (and beyond)\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Sabine Lamm
 ers \, University of Indiana-Bloomington
DESCRIPTION:The Global Feature Extractor (gFEX) subsystem of the ATLAS
  Level 1 Calorimeter trigger is intended to enhance the selectivity of
  the L1 trigger and increase sensitivity to key physics channels.  The
  gFEX identifies large-radius jets\, typical of Lorentz-boosted object
 s\, by means of wide-area jet algorithms refined with subjet informati
 on. The architecture of the gFEX permits event-by-event local pileup s
 uppression for these jets using baseline subtraction techniques compar
 able to those developed for offline analyses. The gFEX architecture is
  also suitable for other global event algorithms such as missing Et an
 d centrality-related variables.<br>
