84954c47 | 9 | // Classe to create the MUON coktail for physics in the Alice muon spectrometer |
9538aedd | 10 | // The followoing muons sources are included in this cocktail: |
11 | // jpsi, upsilon, non-correlated open and beauty, and muons from pion and kaons. | |
12 | // The free parameeters are : | |
13 | // pp reaction cross-section | |
14 | // production cross-sections in pp collisions and | |
15 | // branching ratios in the muon channel | |
16 | // Hard probes are supposed to scale with Ncoll and hadronic production with (0.8Ncoll+0.2*Npart) | |
17 | // There is a primordial trigger wiche requires : | |
18 | // a minimum muon multiplicity above a pT cut in a theta acceptance cone | |
