Description
The scope of the ATLAS tau trigger system at the LHC is most ambitious.
It aims at reconstructing in real time, a matter of seconds, a
detailed picture of the high energy proton proton collisions at the
LHC. Such system is mandatory in order to select efficiently data needed
for discovery of new physics in a proton proton collision environment
where the rates of jets observed in the detector are high and the tau
identification is difficult. New physics scenarios targeted specifically
by the the ATLAS tau trigger system are Standard Model or SuperSymmetric
Higgs production, and production of new exotic resonances.
This contribution will detail how the analysis techniques developed
offline for efficient data analysis have been implemented in the
algorithms which run online at the trigger. In particular, the focus will be
on how to satisfy the requirements imposed by the physics goals while
addressing the limitations from the overall event rate and latency allowed.
The prospects for early running during the first LHC collisions and
trigger evolution from first collisions to stable running will be also
summarized, following change of trigger goals from commissioning of detector
to measurement of Standard Model physics and discoveries.
