Jets/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?)

35 Selections: b-tagging
Two classes of tagging variables can be used: track variables (xT ) and collective (vertex) variables (xV ).The weight of each RoI is computed using the likelihood-ratio method where Ssig and Sbkg are the probability densities for signal (b-jets) and background WT : transverse (d0/sd0 ) and longitudinal (z0) WV : 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 Referee Marzo 2006 Valerio Vercesi - INFN Pavia

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 (1x1033) 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 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 2006 29 May - 1 June 2006 30 October - 2 November 2006 Referee Marzo 2006 Valerio Vercesi - INFN Pavia
