Description

The Jets-without-Jets algorithm presents a novel approach to the determination of jet observables without the need for timely jet reconstruction.  Because it relies on a set of simple sums, the algorithm is well suited to the kinds of fast real-time calculation that are required for a trigger algorithm.  Following the current data taking period, the global feature extractor (gFEX) will be incorporated into the ATLAS Level-1 calorimetry trigger system.  The capacity of the gFEX to process information from the whole calorimetry system on a single board makes it ideal for the determination of whole event quantities.  This presentation will discuss the development of a trigger algorithm that uses the Jets-without-Jets algorithm and the gFEX to model missing transverse energy (MET).
