d599d913 | 20 | // This is a TTask that made the calculation of the Time zero using TOF. |
7aeeaf38 | 21 | // Description: The algorithm used to calculate the time zero of |
22 | // interaction using TOF detector is the following. | |
23 | // We select in the MonteCarlo some primary particles - or tracks in | |
24 | // the following - that strike the TOF detector (the larger part are | |
25 | // pions, kaons or protons). | |
26 | // We choose a set of 10 selected tracks, for each track You have the | |
27 | // length of the track when the TOF is reached (a standard TOF hit | |
28 | // does not contain this additional information, this is the reason | |
29 | // why we implemented a new time zero dedicated TOF hit class | |
30 | // AliTOFhitT0; in order to store this type of hit You have to use the | |
31 | // AliTOFv4T0 as TOF class in Your Config.C. In AliTOFv4T0 the | |
32 | // StepManager was modified in order to fill the TOF hit branch with | |
33 | // this type of hits; in fact the AliTOF::AddT0Hit is called rather | |
34 | // that the usual AliTOF::AddHit), the momentum at generation (from | |
35 | // TreeK) and the time of flight given by the TOF detector. | |
36 | // (Observe that the ctor of the AliTOF class, when the AliTOFv4T0 | |
37 | // class is used, is called with the "tzero" option: it is in order | |
38 | // create the fHits TClonesArray filled with AliTOFhitT0 objects, | |
39 | // rather than with normal AliTOFhit) | |
40 | // Then Momentum and time of flight for each track are smeared | |
41 | // according to known experimental resolution (all sources of error | |
42 | // have been token into account). | |
43 | // Let consider now only one set of 10 tracks (the algorithm is the | |
44 | // same for all sets). | |
45 | // Assuming the (mass) hypothesis that each track can be AUT a pion, | |
46 | // AUT a kaon, AUT a proton, we consider all the 3 at 10 possible | |
47 | // cases. | |
d599d913 | 48 | // For each track in each (mass) configuration |
7aeeaf38 | 49 | // (a configuration can be |
50 | // e.g. pion/pion/kaon/proton/pion/proton/kaon/kaon/pion/pion) | |
51 | // we calculate the time zero (we know in fact the velocity of the | |
52 | // track after the assumption about its mass, the time of flight given | |
53 | // by the TOF, and the corresponding path travelled till the TOF | |
54 | // detector). Then for each mass configuration we have 10 time zero | |
55 | // and we can calculate the ChiSquare for the current configuration | |
56 | // using the weighted mean over all 10 time zero. | |
57 | // We call the best assignment the mass configuration that gives the | |
58 | // minimum value of the ChiSquare. | |
59 | // We plot the weighted mean over all 10 time zero for the best | |
60 | // assignment, the ChiSquare for the best assignment and the | |
61 | // corresponding confidence level. | |
62 | // The strong assumption is the MC selection of primary particles. It | |
63 | // will be introduced in the future also some more realistic | |
64 | // simulation about this point. | |
0e46b9ae | 65 | // |
d599d913 | 66 | // Use case: |
67 | // root [0] AliTOFT0 * tzero = new AliTOFT0("galice.root") | |
68 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
69 | // root [1] tzero->ExecuteTask() | |
70 | // root [2] tzero->ExecuteTask("tim") | |
71 | // // available parameters: | |
72 | // tim - print benchmarking information | |
7aeeaf38 | 73 | // all - print usefull informations about the number of |
74 | // misidentified tracks and a comparison about the | |
75 | // true configuration (known from MC) and the best | |
d599d913 | 76 | // assignment |
