The implementation of the ATLAS missing Et triggers for the initial LHC operation

The trigger system of the ATLAS detector is a three-level architecture in which the decision is taken by custom electronics at the first level whereas the following levels operate in a software environment that is similar to the offline reconstruction program. This paper describes the missing transv...

Descripción
Sumario:The trigger system of the ATLAS detector is a three-level architecture in which the decision is taken by custom electronics at the first level whereas the following levels operate in a software environment that is similar to the offline reconstruction program. This paper describes the missing transverse energy (\MET) triggers in ATLAS for the first data taking in 2009 and 2010 LHC runs, in particular providing the first public documentation of their implementation at all trigger levels.
