DELPHI Event r0026154e0001417
e+ e- ---> Mu+ Mu- , barrel
The two tracks do not deposit detectable energy in the HPC, are minimum
ionizing in the HAB and produce hits in both planes of the MUB.
Both tracks are reconstructed from information in the VD, ID, TPC and OD.
The Mu+ (up-right in x,y) has a momentum of 47.8 GeV/c and the Mu-
(down-left in x,y) has 43.8 GeV/c.
Both are compatible with the beam momentum.
