Theoretical values for the branching ratios of the Z particle:
|
Leptonic decays |
Branching ratio |
| 2 neutrinos | 20 % |
| 2 electrons | 3,67 % |
| 2 muons | 3,67 % |
| 2 tau particles | 3,67 % |
|
Quark decays |
Branching ratio* |
| Total | 69,9 % |
| 2 jets | ~ 40 % |
| 3 jets | ~ 24 % |
| 4 or more jets | ~ 6 % |
* Only the total branching ratio for quarks is a value from the Standard Model. The individual numbers of the branching ratios for events with different number of jets are experimental values.
