FTKSim status and planes FTK Meeting 11/14/2006 F. Crescioli, P. Giannetti, M. Dell'Orso G. Punzi, G. Volpi

FTKSim status V 12: news Space point (SP) problem seems worse: 10 single track events 7000 hits in 7 layers ~ 100 hits per layer w standard digitization We improve the definition of duplicated tracks: Let’s collapse two SP (as being the same SP) if within a distance of: 2 mrad for x coordinates (local ) 1. 5 mm for z coordinates This eliminate a great number of duplicated tracks Reduce only of 1% the total efficiency There are no effects on the parameter resolutions

Dupl. tracks reduction in Bs-->mumu sample The duplicated tracks (green) now represent ~1% of total amount of tracks No effects over not associated tracks (red). Probably other reasons for them. Implement the event Display to understand them

WH->munuuu and WH->munubb samples Similar effects over dupl. tracks H->uu, bb samples bb uu

IP distributions for Truth, i. Pat. Rec and FTK The d 0 distribution for “all tracks” still have some problems confronting: H>bb, uu The problem is due to the d 0 distribution of not associated tracks Under investigation, probably in the new training. TRUTH IPATREC FTK FAKE PROB.

WH->munuuu and WH->munubb samples With “FRANCESCO digitization” To see if fakes are reduced EVENT DISPLAY? V 12 NEWs: Different geometries available. First of all try to use Rome-final geometry (the one used with V 10) and see if the old training is compatible. Did Meena use the Rome-final geometry when did try version 11? If it works Meena can try the new b-tagging study and start immediately to work at page 9, studying Bs mu mu , WH……. If it does not work do the training again

IF we have to DO the training again a) Update Ftk. Sim. Wrap to produce from Athena V 12 FTKsim input file format Activate the 2 nd pixel layer and dump all the layers (Done- to be checked) Dump raw hits (R-PHI Layers and stereo Layers) (Done- to be checked)? Ipatrec Dump: is it possible to run Ipat. Rec without TRT information? (Done- to be checked)? - Use of new features – do they solve the V 10 problems? : 1. start with V 12 to check we can reproduce the V 10 results-proposal: Guido tests new data with old configuration to pass FTKsim to Chicago generates 100 ktracks, new patterns, new constants (to learn the training and speed up the tests. Guido will be out sometime, Francesco coming back next week) even if NOT efficient pattern bank, can we find any track in events? 2. Guido-Francesco: modify FTKsim to use the new pixel layer instead of the inner SCT layer and test again: Guido tests new data with new configuration to distribute FTKsim Repeat a short training, generate pattern bank, new constants. even if NOT efficient pattern bank, can we find any track in events? 3. IF 1&2 OK: Start full training and allow Meena repeat her b-tagging ? Wait for raw-hit test? Can raw-hit test go in parallel with 1 -2?

Study again FTK performances on fakes using raw hits. CAN we do this in parallel to the previous page? Move Francesco & someone from Chicago on this or everybody on space point new simulation? Not use any clustering and use only clean up after TF. Processing time? Track resolution? Develop & include in FTKsim an FTK clustering algorithm thinking to the hardware implementation (DATA-FORMATTER in the next slide)? Inside the proposal: Which layers (& how many)? We know it is better to reject the central ones. Which is the impact on fakes and processing time? Which is the pattern bank (road) size ?

WHEN the FULL training will be done (efficient pattern bank and good constants) with millions of single tracks…. Measure again FTKSIM performances for: (a) Bs (done for V 10 -Francesco-Guido – redo it for V 12) (b) uu, bb jets from SM WH (done for V 10 -Meena-Guido – redo it for V 12) (c) taus ? (d) energetic u-b-jets? Supersymmetric Higgs at high masses? (e) other samples? Different samples could require different FTK features ! Taus or energetic b-jets can be more demanding than WH events ! Produce new Physics samples and simulate FTK !

CONCLUSIONs: sequence of jobs 1. HIGH PRIORITY: Check new link between FTKsim & Athena V 12 2. Start the FULL training or use raw data to check their status (takes time) before producing millions of tracks? 3. Study FTKsim as a function of possible options (which/how many layers…, clustering y/n…, which algorithms…). 4. Check FTKsim performances on Physics samples
