DELPHI Event r064307e010647
from the 130-140 GeV Run
e+ e- ---> q qbar
From 136.2 GeV run.
q-qbar event with 4 clear jets.
Missing quantities suggest that a single particle has been lost in the
direction of jet 1 (in red) with a momentum around 16 GeV/c.
The 40 degree taggers also indicate that some energy went into this
direction.
This event was kept in all parallel analysis looking for dijet systems
compatible with equal masses.
A 5C fit leads to a common dijet mass in the range of 50 to 60 GeV/c**2
