7 | // Class AliQuarkoniaEfficiency | |
8 | // | |
9 | // This class will provide the quarkonia reconstruction efficiency | |
10 | // in ALICE without acceptance consideration | |
11 | // for different resonances : | |
12 | // kJpsi | |
13 | // kPsiP | |
14 | // kUpsilon | |
15 | // kUpsilonP | |
16 | // kUpsilonPP | |
17 | // for some vector mesons : | |
18 | // kPhi | |
19 | // kOmega | |
20 | // different decay channels: | |
21 | // kDimuon | |
22 | // kDielectron | |
23 | // different trigger configurations: | |
24 | // kSinglePlusLpt, kSinglePlusHpt, kSinglePlusApt, | |
25 | // kSingleMinusLpt, kSingleMinusHpt, kSingleMinusApt, | |
26 | // kSingleUndefLpt, kSingleUndefHpt, kSingleUndefApt, | |
27 | // kPairUnlikeLpt, kPairUnlikeHpt, kPairUnlikeApt, | |
28 | // kPairLikeLpt, kPairLikeHpt, kPairLikeApt | |
29 | // different parameterizations: | |
30 | // kFlat | |
31 | // kCDFscaled | |
32 | // kCDFscaledPP | |
33 | // | |
34 | // | |
35 | // Reconstruction efficiency has been evaluated by means of a flat | |
36 | // y and pt distribution of quarkonia in -4 < y < -2.5, | |
37 | // 0 < pt < 20 GeV/c. Weights have been used to evaluate the | |
38 | // reconstruction efficiency in different parameterizations. | |
