The current state-of-play is summarised here and new results, as they arrive, will be indicated. Thus, of necessity, it is an evolving document. ---+ Studies ---++ LAr Studies (for Phase-I TDR) ---+++ Signal Feature Reconstruction |*Study*|*Status*|*People*| |Filter algorithms and energy resolution| | | |Pile-up and noise filtering| | | |Out-of-time pile-up corrections| | | |Impact on energy resolution from phase-shift and jitter| | | |Dynamic range and quantization scale | | | |BCID| | | |Signal saturation| | | |Optimization of signal reconstruction in different eta regions and calorimeters| | | ---+++ EM Trigger Performance |*Study*|*Status*|*People*| |Shower shape analysis in EM layers| | | |Optimization of shower shape variables in different eta regions| | | |Energy dependency of R_eta algorithms| | | |Multi-dimensional discriminants| | | |Clustering algorithms for HL-LHC| | | |Dependency on quantization scale| | | ---+++ Jet Trigger Performance |*Study*|*Status*|*People*| |Evaluation jet reconstruction algorithms in inclusive triggers| | | |Gaussian filtering and turn-on curves| | | |Pileup background subtraction| | | |Effects of quantization scale| | | |Multi-jet trigger efficiency recovery| | | |Jet energy scale and calibration| | | ---+++ MET Trigger performance |*Study*|*Status*|*People*| |Resolution dependency on layer weighting and layer pT thresholds; Eta dependency| | | |Impact of FCAL granularity on resolution and turn-on curves| | | |Effects of BC mis-identification on resolution| | | |Effects of ADC quatization scale| | | ---+++ Tau Trigger Performance |*Study*|*Status*|*People*| |Discriminant variables for tau identification (em radius, core energy fraction, radius, cluster mass type, em fraction, sub-clusters)| | | |Electron veto by em isolation and em fraction| | | |Dependency on eta regions and detectors| | | ---+++ Impact of single and di-em trigger performance on physics searches |*Study*|*Status*|*People*| |H -> gamma gamma| | | |H -> Z gamma| | | |H -> tau tau -> ee| | | |H -> WW* -> e nu| | | ---++ Supporting h/w design choices ---+++ xFex TOB output multiplicities *Priority*: initial results are needed by early summer 2014 as input to the eFex prototype (scheduled for manufacture early 2015) design process. *Description*: this activity will study the connectivity requirements (including bandwidth, data formats, overflow handling, etc.) between the eFEX modules and Atlas.L1Topo modules and the potential impact on physics triggers of any constraints or limitations in this area. The study will use realistic emulations of Trigger Objects reflecting the desired physics goals and take into account the level of pileup that is anticipated. The simulation results will feedback into the eFEX design process and as such will be both timely and have significant importance in the upgrade of Atlas.L1Calo at Phase-I. ---+++ 1 Bunch train effects 1 Consequences for Atlas.L1Calo of LPDS design choices 1 The gFex ---++ Supporting algorithm choices ---+++ e/γ ---+++ τ ---+++ Jet ---+++ Missing Et (and other global event quantities) ---+ Datasets <!-- Add the main topic here. i.e. create some new headings as follows: --> <!-- *********************************************************** --> <!-- Do NOT remove the remaining lines, but add requested info as appropriate --> <!-- *********************************************************** --> --- <!-- For significant updates to the topic, consider adding your 'signature' (beneath this editing box) --> *Major updates*:%BR% -- Main.RobinMiddleton - 19 Nov 2014 <!-- Person responsible for the page: Either leave as is - the creator's name will be inserted; Or replace the complete REVINFO tag (including percentages symbols) with a name in the form Main.TwikiUsersName --> %RESPONSIBLE% %REVINFO{"$wikiusername" rev="1.1"}% %BR% <!-- Once this page has been reviewed, please add the name and the date e.g. Main.StephenHaywood - 31 Oct 2006 --> %REVIEW% *Never reviewed* %STOPINCLUDE%
