Jet Trigger Analysis for the ALICE Electromagnetic Calorimeter

The analysis of jets in ultra-relativistic heavy ion collisions with the ALICE experiment at the LHC requires a sophisticated trigger scheme to acquire a high statistics sample of high p$_{t}$ jets. This can be implemented using the large area electromagnetic calorimeter (EMCal)~proposed by the ALICE-USA Collaboration. A Level 1 EMCal jet trigger will be discussed and compared to an idealized leading pi0 trigger in order to elucidate the underlying trigger behavior. The effect of fluctuations in the rather large background will be explored. It will be shown that a Level 1 trigger can select appropriate jet events efficiently while reducing the data rate to the required level. The necessity of a further reduction of the data rate requires the use of an efficient higher level multiplicity dependent jet trigger which will be discussed.
