| 1 | + HFT VMC Embedding status and plans. |
| 2 | + |
| 3 | +1. HFT Simulators: |
| 4 | + Pxl fast simulation with status tables, |
| 5 | + Ist slow simulation, |
| 6 | + Sst fast. |
| 7 | +2. The tests of simulated charm particle decays and their reconstrution have been done with |
| 8 | + a. misaligned (Real) geometry, and |
| 9 | + b. the primary vertex using MC one |
| 10 | + c. pT distribution (mTsq) : dN/dmT^2 = exp(-mT/T) with T = 0.457 GeV/c |
| 11 | + d. pT range for D/Ds : [1,10] GeV/c |
| 12 | + Lambda_c : [2,10] GeV/c |
| 13 | + e. 0 < phi < 2pi; |eta| < 1 |
| 14 | +3. MuDst files are located on HLT farm at |
| 15 | +D0-> K+K- /net/l401/data/scratch2/fisyak/reco/2016B/D02KmTsqReal |
| 16 | +D0-> K0s K+K- /net/l401/data/scratch2/fisyak/reco/2016B/D0K0s2KmTsqReal |
| 17 | +D0-> K0s pi+pi- /net/l401/data/scratch2/fisyak/reco/2016B/D0K0s2pimTsqReal |
| 18 | +D0-> K-pi+ /net/l401/data/scratch2/fisyak/reco/2016B/D0KpimTsqReal |
| 19 | +D+-> K0s pi+ /net/l401/data/scratch2/fisyak/reco/2016B/DK0spimTsqReal |
| 20 | +Ds+-> K0s K0s pi+ /net/l401/data/scratch2/fisyak/reco/2016B/DsK0sK0spimTsqReal |
| 21 | +Ds+-> K0sK+ /net/l401/data/scratch2/fisyak/reco/2016B/DsK0sKmTsqReal |
| 22 | +Ds+-> K+K-pi+ /net/l401/data/scratch2/fisyak/reco/2016B/DsKKpimTsqReal |
| 23 | +Lambda_c+->Lambda 2pi+pi- /net/l401/data/scratch2/fisyak/reco/2016B/Lc3pimTsqReal |
| 24 | +Lambda_c+->K-pi+p /net/l401/data/scratch2/fisyak/reco/2016B/LcKppimTsqReal |
| 25 | + |
| 26 | +Decays forced: |
| 27 | + K0s -> pi+ pi- |
| 28 | + Lambda -> p pi- |
| 29 | + |
| 30 | +4. Maksym and Iouri are checking the above data sets. They agreed to present |
| 31 | +the reconstruction efficiencies for the above channels on HF PWG. |
| 32 | +This study will define a priority list for embedding. |
| 33 | + |
| 34 | +5. Pavol Frederic using Ideal geometry is studying more extensive list of open charm decay channel |
| 35 | +in order to check / update the priority list. |
| 36 | + |
| 37 | +6. Release TFG17g has been created on both RCF (gcc 4.8.2 and gcc 4.9.2) and HLT (gcc 5.2.1) |
| 38 | +for i32 and x86 both debug and optimized. This release has been frozen. |
| 39 | +People who would like to stay with stable environment are invited to use TFG17g. |
| 40 | + |
| 41 | +7. We are planning to use HLT cluster to do embedding of the selected channel for |
| 42 | +days 125-134 (1462416 events). |
| 43 | + One channel takes ~2 days of processing on HLT farm. |
| 44 | +24 (h/day) * 3600 (h/sec) * 475 cpu / 25 (secs/event/cpu) / 1e6 (events) = 1.64 days/(1Mevent) |
| 45 | + It is planning that the production on HLT farm will be managed by Hongwei. |
| 46 | + |
| 47 | +8. Event selection, Primary vertex with |
| 48 | + |Z| < 6 cm, |
| 49 | + |Z - Z_VPD| < 3 cm, |
| 50 | + sqrt(X^2 + Y^2) < 1 cm, and |
| 51 | + sqrt(sigma_X^2 + sigma_Y^2) < 0.0050 cm |
| 52 | + TriggerId selection : 520001, 520011, 520021, 520031, 520041, 520051 (Jamie, Xin) |
| 53 | + |
| 54 | +9. The first pass of embedding of Lambda_c+->K-pi+p has bee done. |
| 55 | +MuDst files are located at |
| 56 | + /net/l401/data/scratch2/fisyak/reco/2016Embedding/LcKppimTsq/ |
| 57 | +The sample contains 665784 events. |
| 58 | + |
| 59 | +Maksym and Iouri are checking the production. |
| 60 | +I have one concern with this production: |
| 61 | + I don't see Ist hits with non zero IdTruth in embedding. |
| 62 | +I am sure that MC hits are propagated through Ist reconstruction. |
