DELPHI Z0 PEAK EVENT

DELPHI Event r0026154e0003163


e+ e- ---> q qbar , 2 jets , 3 muons
Hadronic event with two clean jets.

One jet (down left) has a Mu+ (7.4 GeV) and a Mu- (2.4 GeV) both leaving no deposit in the HPC, minimum ionizing in the HAB and producing hits in both planes of the MUB. They have an invariant mass of 0.65 GeV.

The second jet has a Mu- (5.4 GeV) with a small deposit in the HPC, minimum ionizing in the HAB and hits in both planes of the MUB.

Could be an example of b --> c + Mu in both jets,
followed by c --> s + Mu in one of them.
