from the 130-140 GeV Run


e+ e- ---> q qbar gamma, 4 jet
From 130.4 GeV run.
q-qbar 3-jet event from radiative return to the Z0.
The gamma is lost in the beam pipe and some energy is unmeasured due to the TPC Theta crack (producing a missing Pt of 8 GeV).

Characteristics :
Evis = 92 GeV , Mvis = 90 GeV
Emiss = 38 GeV, Mmiss = 33 GeV, P_{t,miss} = 8 GeV.
