-- HamishGordon - 22 Jul 2008 results obtained 23rd July

Cuts: signal 705 at peak, background 280 at peak and 260 at maximum

No cuts: signal 1000 at peak, background 30500

Results obtained 24th July

Mass cuts

1. Dstar: |Invariant mass of DPi minus PDG mass of Dstar|<50MeV 2. D0: |Reconstructed mass of Dstar minus reconstructed mass of D0 minus expected mass difference from PDG|<20MeV 3. D0: |Invariant mass of KPi minus PDG mass of D0|<50MeV

All cuts applied to D0 (cuts 2 and 3): 300 signal events, 2 ghosts, no other visible background.

All cuts applied to D*+: 210 signal events, 12-15 background events.

No specific mass cut applied to D0: 5500 signal, 1000 background (ie no cut 2 or cut 3)

No specific mass cut applied to D*+: 210 signal, 200 background (no cut 1)

No mass cut applied to D0 when reconstructing Dstar: still 210 signal, 200 background, no significant effect (no cut 3)

Cut 2 but not cut 3 applied to D0: 260 signal, 12 background

Cut 3 but not cut 2 applied to D0: 5500 signal, 100 background, narrow+isolated.
