Signal P1 has the following charateristics:
M0=60, M1/2=190, tan(beta)=3, A0=0, mu > 0
and is used in all plots/tables as the standard SUSY point.
The masses at this point are
Mchargino=119 GeV
Mneutralino=122 GeV
Leading Electron ET
Figure shows the leading electron's transverse energy distribution
for dielectron events with missing transverse energy
greater than 15 GeV and Z-mass veto.
(missing ET > 15 GeV , 20 <Mee< 76 OR Mee> 106)
Missing ET
Figure shows the missing transverse energy distribution
for dielectron events with missing transverse energy
greater than 15 GeV and Z-mass veto.
(missing ET > 15 GeV , 20 <Mee< 76 OR Mee> 106)

Final Plots after all Selections
Missing ET
Figure shows the missing transverse energy distribution
for dielectron + track events after all selections (except this one)
have been made. We keep events with missing ET > 20 GeV.
Leading Invariant Mass
Figure shows the leading opp-sign invariant mass distribution
for dielectron + track events after all selections (except this one)
have been made. We keep events with 20 <Mee< 76, OR Mee > 106.
Min. MT
Figure shows the minimum transverse mass (of electron/track with missing ET) distribution
for dielectron + track events after all selections (except this one)
have been made. We keep events with min MT > 10 GeV.
