invM-vs-vtxz-single-signal-point.png

• tanLambda of conv vtx to separate bkgd from signal?
  • invM?
  • Opening angle at vertex
  • delta(tanLambda)
  • z0/tanLambda
  • Point to target
• Need to quantify number of signal events so that we can see if S/sqrt(B) is high enough to do a selection.
  • Just use a "selection" z cut to get a S and then we can compare that to B with the same selection.
• We want "a number" to make a decision
• How to select against the background? What selections could reduce background without reducing the signal efficiency further?
