DELPHI Event r063930e004022
from the 130-140 GeV Run
e+ e- ---> Tau+ Tau- gamma
From 130.4 GeV run.
Tau+ Tau- event, with Tau- --> Mu- nu and
Tau+ --> 3Pi Pi0 nu.
The Taus form an angle of about 120 degree, typical of a radiative return to
the Z0.
The Mu- has 16 GeV/c, is MIP in the calorimeters and has hits associated in
the MUB.
The 3Pi system has 37 GeV energy.
It is accompanied by an energy deposit of 14 GeV in the HPC.
The (3Pi + Pi0) system gives a mass of about 1.6 GeV.
Characteristics :
Evis = 66 GeV.
