DSG with njet cut

Reduce background to 10%: MET cut of 80 GeV

Without MET cut

with MET cut of 80 GeV

poor man's fit to background reduction dependent on hyp_met cut

• expo fit:
  • take met cut values as x values
  • take corresponding event yields of all samples except LM? as y values
  • let ROOT fit with "expo" ( f(x) = exp(p0+p1*x) )

• use all fit, calculate MET cut for 10% background, which results in MET_Cut = (ln ( f(x) ) - p0)/p1 = ( ln(10)-6.339 ) / -0.044444 = ~90 GeV
• use em fit, calculate MET cut for 10% background, which results in MET_Cut = (ln ( f(x) ) - p0)/p1 = ( ln(10)-6.234 ) / -0.04697 = ~84 GeV

• these are numbers prepared by Johannes

• these are numbers reproduced by OLI (just running the NtupleMacros WW code)

• these are Oli's results when adding LM1/2/4 from V00-05-00 (not merged though)

Oli: running again at CERN

• running again at CERN with all samples
• noticed that selection is not the same as before

• suspect added cut: more than two tracks is responsible for LM2/4 yielding no entries?

Oli: rerun 081104 with head, require ntrk > 2 now
