20 | - Decay probability is counted once if muons are decay products | |
21 | of the same mother particle. Otherwise, it's counted twice. | |

423 | <BR>It corresponds of the weight 0.06 given for example in gener->AddGenerator(jpsi,"J/Psi", | |
424 | 0.06); from the config.C macro. | |
425 | <BR>In this example R=0.06 | |
426 | ||
427 | <P>M = the rate of the mother production. This number depend on : | |
428 | <BR> - the number of generated events --> fParentWeight=1./Float_t(fNpart) in AliGenPythia.cxx . This | |
429 | is a normalization to 1 of the number of generated particles. | |
430 | <BR> - the kinematic bias coming | |
431 | from the y and Pt cuts. Method AliGenPythia::AdjustWeights() in AliGenPythia.cxx | |
432 | <BR>(in AliGenParam.cxx this 2 things are taken into account in fParentWeight | |
433 | = fYWgt*fPtWgt*phiWgt/fNpart ) | |
434 | ||
435 | <P>Br = the branching ratio in muon from the mother decay</UL> | |
436 | ||
437 | <P><BR>In this method, part->GetWeight() = M*Br | |
438 | <UL> </UL> | |
439 | Next --> | |
440 | <BR>The weight of the dimuon depends on the correlation between muons | |
441 | <BR> | |
442 | <UL>If the muons are correlated and come from a resonance (for example | |
443 | J/psi -> mu+ mu-) , the weight of the dimuon is the weight of one muon then | |
444 | <BR>w12= R*M*Br = w1* R1 (in this method this gives part1->GetWeight()*fRate1) | |
445 | ||
446 | <P>If the muons are correlated and come from a charm or a bottom pair then | |
447 | w12 = M*R*Br1*Br2 = w1*w2*R1/M1 | |
448 | <BR>(in this method this gives wgt/(Parent(part1)->GetWeight())*fRate1). | |
449 | Indeed the 2 muons come from the same mother so the | |
450 | <BR>weight of a DD~ or BB~ is M*Br and they are no correlation in the decay | |
451 | (Br1*Br2) | |
452 | ||
453 | <P>If the muons are not correlated w12 = M1*M2*R1*R2*Br1*Br2 = w1*w2*R1*R2 | |
454 | (in this method this gives wgt*fRate1*fRate2) | |
