X(2000)0 Mass
- X(2000)0: The combination of tracks yielding a mass closest to the X(2000)0.
- 10000 generated events: ~49% reconstruction efficiency.
- However, very significant high-mass tail.
π0 Mass
- π0: The combination of tracks yielding a mass closest to the π0.
- Significantly worse resolution than originally.
- π0: Original version on b1pi wiki page:
%gamma; Reconstruction
- %gamma;'s were reconstructed with p & E = 0 until a fix by David Lawrence this morning.
- For each of the generated photons that were matched with reconstructed photons, Δp (generated - reconstructed) vs generated p:
