1 Physics Validation

2 Validations 18/12/13: DC14 (1) 5 validation tasks for this week: Several DC14 simulation tests, grouped into 3 tasks 2 tasks on IBL/ITK digi+reco bugfix (ttbar only) (1) Test of simulation in 17.7.3.1, which will be used for DC14. Without pileup and no changes expected. Test: s1860_s1862_r5143 (17.7.3.1, 17.3.12.1) - GEO-21-00-03, FS off Ref: s1859_s1862_r5143 (17.7.1.2, 17.3.12.1) - GEO-21-00-03, FS off ATLPHYSVAL-39 (2) Check impact of frozen showers in 17.7.3.1 (w/o pileup) Ref is test from task 1. Similar changes expected to last FS validation Test: s1861_s1862_r5143 (17.7.3.1, 17.3.12.1) - GEO-21-00-03, FS on Ref: s1860_s1862_r5143 (17.7.3.1, 17.3.12.1) - GEO-21-00-03, FS off ATLPHYSVAL-39 19/12/2013Simulation Steering Group Meeting2

3 Validations 18/12/13: DC14 (2) (3) Several technical simulation changes for 17.7.3.1/.2 AthenaMP-II, New GEO tag naming, SLC6 release. Reference is the test from task 1. No changes expected in all cases. Test 1: (AthenaMP): s1860_s1862_r5143 (17.7.3.1, 17.3.12.1) - GEO-21-00-03, FS off, no pileup Test 2: (SLC6): s1866_s1862_r5143 (17.7.3.2, 17.3.12.1) - GEO-21-00-03, FS off, no pileup Test 3: (GEO naming): s1865_s18XX_r51XX (17.7.3.2, 17.3.12.2) - GEO-21-00-03, FS off, no pileup Ref: s1860_s1862_r5143 (17.7.3.1, 17.3.12.1) - GEO-21-00-03, FS off ATLPHYSVAL-39 Geo naming task not run in time due to crash in HITS merging Fixed in 17.6.51.2 (thanks for quick turn around) Running merging and digi+reco for ttbar scout Hoping to be able to have TAG-level comparison by Friday Since this is only a technical change this would probably be sufficient 19/12/2013Simulation Steering Group Meeting3

4 Validations 18/12/13: IBL/ITK 4) Check of vertex bugfix for ITK digi+reco in 17.3.10.1. Truth info accidentally used re-ordering the vertex container which may have caused a small bias in some samples, resulting in the primary vertex ID being more efficient than would be expected using usual sum(pT^2) criteria. Only small changes in vertex efficiency expected Test: s1636_r5087 (17.3.10.1,AtlasProductuion) - No pileup, ttbar only Reference: s1636_r4528 (17.3.10.1,AtlasProductuion) - No pileup ATLPHYSVAL-52 (5) Check of vertex bugfix for IBL digi+reco in 17.3.10.1.1 Same issue as task 4. Again small changes in vertex efficiency expected. Test: s1638_r5119 (17.3.10.1.1,IBLProd) - No pileup, ttbar sample only Reference: s1638_r4514 (17.3.10.1.1,IBLProd) - No pileup ATLPHYSVAL-52 19/12/2013Simulation Steering Group Meeting4

5 Validations 29/11/13 (2) (3) Validation of GEO-21 with MC11 configuration with pileup Follow up on previous validation of MC11 with GEO-21 without pileup a Test : s1786_r4980 (17.2.11.7.1, 17.0.7.3 with GEO-21) Reference: s1372_r3043 (16.6.7.18, 17.0.5.6 with GEO-18) ATLPHYSVAL-41 (4) Validation of digi+reco in 17.2.12.1 for mc12 prod (GEO-20) Two tests: r5079 with the nominal configuration but digi+reco in the latest release r5080 which includes technical changes to DB access via frontier in digi+reco (including trigger DB). Test1 : s1469_r5079 (17.2.0.2, 17.2.12.1) Test2 : s1469_r5080 (17.2.0.2, 17.2.12.1) Reference: s1469_r4764 (17.2.0.2, 17.2.11.1) ATLPHYSVAL-50 19/12/2013Simulation Steering Group Meeting5

6 Overview Have most results: Electrons, photons, MET, muons (except 1/4), tracking (except 4), secondary tracking, jets (except 4/5), tau (except 2/3), b-tagging, top (except 4), Higgs (except 4) Physics/CP groups really pushed hard to get this validated Still waiting for a few results: Jets(4/5), muons (1/4), tracking (4), tau (2/3), SUSY, top (4), Higgs (4), exotics Ones in bold relavent for DC14 Things looking very good from what we can see so far for all DC14 tasks and IBL/ITK digi+reco: 19/12/2013Simulation Steering Group Meeting6

7 17.7.3.1 Simulation In general looks good b-tag yellow but diffs similar to usual Largest diff seen is increase in muon efficiencies at high p T Similar for all muon types Some small diffs in tracking for ganged pixels, holes, outliers (true for all tasks) 19/12/2013Simulation Steering Group Meeting7

8 17.7.3.1 Simulation: AthenaMP/SLC6 Some small differences seen but pretty much all within stat uncertainties An example of a largest one seen for SLC6: pixel holes 19/12/2013Simulation Steering Group Meeting8

9 Frozen Showers in 17.7.3.1 (1) Some diffs in E response (linearity/uniformity) for forward elecs Uniformity (right) similar to seen in 17.7.1.2 validation (bottom) Larger difference for linearity seen by egamma (left) but not for SM (later) Shape clearly different to previous results too 19/12/2013Simulation Steering Group Meeting9 Test (FS on) Ref (FS off)

10 Frozen Showers in 17.7.3.1 (1b) Differences noticeably larger than MC12 new FS library validation 19/12/2013Simulation Steering Group Meeting10

11 Frozen Showers in 17.7.3.1 (2) SM Z->ee also see difference in linearity for fwd elecs But here similar to 17.7.1.2 validation (bottom) Note: colors switched wrt egamma; RHS plot definition inverted wrt previous 19/12/2013Simulation Steering Group Meeting11 Test (FS on) Ref (FS off)

12 Frozen Showers in 17.7.3.1 (2b) Again significantly larger differences in linearity than in MC12 19/12/2013Simulation Steering Group Meeting12

13 Frozen Showers in 17.7.3.1 (3) SM Z->ee further see difference in resolution for fwd elecs Again similar to previous validation (bottom) 19/12/2013Simulation Steering Group Meeting13 Test (FS on) Ref (FS off)

14 Frozen Showers in 17.7.3.1 (3b) Resolution changes similar to those seen in MC12 19/12/2013Simulation Steering Group Meeting14

15 Frozen Showers in 17.7.3.1 (4) Egamma/Z -> ee linearity differences are clearly larger than those seen in MC12 Photon results marked green but haven’t seen plots to check in depth the level of differences Given the above would suggest to not use FS for DC14 at this point 19/12/2013Simulation Steering Group Meeting15

16 New Geometry Naming Include TAG comparison if get in time 19/12/2013Simulation Steering Group Meeting16

17 IBL/ITK digi+reco Several groups struggling to run on task 4 (ITK) Likely due to changes to job options needed for IBL For IBL task (5), things look good so far Including vertex-dependent tracking variables Don’t yet have a vertex distribution itself Unfortunately unable to run b-tagging for these samples Mistakenly included "JetTagNtuple/preInclude_Reco_trf_IBL.py” which was found previously to disable some required containers. 19/12/201317

18 Upcoming validations + Plans for next meeting 19/12/2013Simulation Steering Group Meeting18

19 Upcoming Validations (1) Validation of AFII for DC14 in 17.7.2.1/17.7.3.1. Reminder: no validated AFII with pileup so proposed plan is: AFII vs latest validated AFII in 17.6.0.7 without pileup AFII vs validated G4 in 17.7.3.1 without pileup to check expected AFII diffs AFII with pileup vs G4 with pileup ATLPHYSVAL-37 Sample A done for 17.7.1.2 Probably want to rerun with 17.7.3.1? Can run these samples over holiday Continue run-dependent conditions tag validation for simulation Disentangle effect of beamspot change & other conditions changes by: MC12b simul and digi+reco conditions tag with override of BS to new tag Run-dep simul & digi+reco conditions tag with override of BS to MC12b tag Sample A reco running MC11, MC10 after MC12 validated MC10 with full sample A (changes in MET); others only tracking validation (BS) ATLPHYSVAL-34 18/12/201319

20 Upcoming Validations (2) Validation of new TRT digi+reco code in 17.3.12.Y In parallel with run-dep conditions tests as requires new conditions tag ATLPHYSVAL-34 Waiting for cache Check new GEO naming for simul (17.7.3.1) & digi+reco (17.3.12.2) Depends on if get results of TAG-level validation before holidays. ATLPHYSVAL-43 Check digi+reco in 17.3.12.1 Plan to properly validate by comparing to last validated digi+reco Already needed to use for 17.7.3.1 simul validation (new GEO + 64 bit ID) Sample A done with GEO-20 to compare to validated 17.2.12.1 Do we want to redo? GEO-21? Pileup? New Reco_tf.py (being validated in separate tasks – see next slide) ATLPHYSVAL-45 18/12/201320

21 Upcoming Validations (3) Validation of new Reco_tf.py and Digi_tf.py in 17.2.12.1 Two tests: digi and reco in two separate steps or one combined step ATLPHYSVAL-56 Sample A reco running Validate updated IBL GEO + code (2 steps) for run 2 DC14 ATLASPHYSVAL-33ATLASPHYSVAL-33: simul & digi+reco in 17.3.12.1 ATLASPHYSVAL-15ATLASPHYSVAL-15: simul in 17.7.3.1 & digi+reco in 17.3.12.Y Still two steps? Waiting for digi+reco cache Validation of overlay in 17.2.11.15 Will have two references: previous overlay + standard MC12 simul Since overlay samples only use HCP data a pile up reweighting is needed HCP GRL must also be applied to the overlay ones (since comes from data) Sample A done ATLASPHYSVAL-49 18/12/201321

22 Upcoming Validations (4) Validation of ITK in 17.7.3.1 Needed to allow non-Gaussian beamspot. Slightly longer term ATLPHYSVAL-53 19/12/2013Simulation Steering Group Meeting22

23 First Meeting Plans What are priorities for first post-Christmas meeting? Monday 13 th Jan (brought forward to gain some time) Possible tasks (samples available or can be run over holiday): AFII simulation New digi and reco transforms 17.3.12.1 digi+reco Run-dependent conditions in MC12b New GEO naming (depending on TAG-validation) Overlay Maybe slightly too many for one meeting Might squeeze in if don’t need to do GEO-naming Should really get overlay done If we need to postpone something, which one? 19/12/2013Simulation Steering Group Meeting23
