30 Referee Marzo 2006 Valerio Vercesi - INFN Pavia 30 Selections: LVL2 Selections: LVL2 Implemented curvature radius instead of sagitta More suitable for the endcap, recover efficiency in the barrel Same algorithm across ± 2.4 in Endcap extension in progress Combined reconstruction ( Comb) with ID Refine the Fast p T by means of ID data sharper 6 GeV threshold Resolution New LUTS for Radius Slightly worse than Resolution is OK for Standard sectors Turn-on curves comparable with Resolution is OK for Standard sectors Worse efficiency in the feet region (Special Sectors)

33 Referee Marzo 2006 Valerio Vercesi - INFN Pavia 33Jets/Taus/ETmiss LVL2 calo algorithm for taus recently separated from egamma Ongoing performance studies for selection strategies on variables At present only EM calibration for cluster energies: need for a tau calibration (also for EF, H1 style as in the offline mode?) First implementation of EF seeded TrigtauRec is already working making use of offline tools Once the selection strategies are defined, physics trigger-aware analyses (studying the effect of the hadronic tau trigger) can be performed Three different strategies (concerning the data preparation) are being considered Read out calorimeter and unpack the cells (unpacking time may dominate) Read out calorimeter, get Ex/ Ey calculated in ROD (faster but … resolution?) Read out TriggerTower from LVL1 Preprocessor Ongoing work to define and studies general strategy for pre-scales, in particular for jet objects

34 Referee Marzo 2006 Valerio Vercesi - INFN Pavia 34 Jet triggers and prescales

35 Referee Marzo 2006 Valerio Vercesi - INFN Pavia 35 Selections: b-tagging Two classes of tagging variables can be used: track variables (x T ) and collective (vertex) variables (x V ).The weight of each RoI is computed using the likelihood- ratio method where S sig and S bkg are the probability densities for signal (b-jets) and background W T : transverse (d 0 / d0 ) and longitudinal (z 0 ) W V : secondary vertex energy and mass (statistical approach) Recent work to combine SimpleVertex (1-dim fit) and VKalVrt (offline algorithm adapted to LVL2) Impact parameters Impact parameters + probabilistic vertex Impact parameters + VKalVrt/SimpleVertex combined

36 Referee Marzo 2006 Valerio Vercesi - INFN Pavia 36 RoI Based B-physics Aim: use the calorimeter to identify regions of the event containing B decay products EM RoI for e and gamma. Jet RoI for hadronic B-decays Keep multiplicity low, to minimize data transfer and cpu, whilst maximising efficiency for events used in physics studies multiplicity= 1-2 The effect of different thresholds (EM&HAD and the jet RoI size on this multiplicity was studied using Rome data (1x10 33 ) with the new TTL LVL1 simulation and pile up The requirement on multiplicity implies an ET threshold of ~ 2GeV for LVL1 EM RoI RoI Multiplicity LVL1 Threshold Energy (GeV) Towerthresh=500MeV (default) Towerthresh=750MeV Towerthresh=1000MeV LVL1 EM RoI multiplicity vs. ET cut

38 Referee Marzo 2006 Valerio Vercesi - INFN Pavia 38 Trigger & Physics Weeks To proceed with the implementation of the guidelines of the ATLAS Operation Model, it has been recently proposed to have few-day trigger workshops in 2006, where the full experiment gets together to discuss trigger issues It was also considered good to couple these meetings to the physics workshops organized since some time by Physics Coordination, in order to strengthen more and more the links between trigger, (combined) detector performance and physics The aim of these weeks is to bring together trigger, detector performance and physics studies, and to expose trigger issues and strategy to a broad ATLAS audience Defined dates March May - 1 June October - 2 November 2006
