[Frost] meeting tomorrow

[Sungkyun Park]

Hi Eugene,

   I have found the missing mass of pi0 in topology gamma p -> p X and butanol target.
   The pi0 mass 162 MeV
  
    Michael Dugger -> pi0 (no momentum restriction) = 163 MeV
                                pi0 ( momentum > 600 MeV) = 157 MeV
    Hideko Iwamoto -> pi0 ~ 168 MeV
    Jo McAndew     -> pi0 ~ 176 MeV

I also tried to find out the missing mass of pi+ and pi- in topology  gamma p -> p pi+ pi-
The pi+ mass I found is 144 MeV and the pi- mass is 142 MeV.
It is very strange why pi0 mass has a big difference with real particle and pi+ and pi- has a very similar value in the same code. 

Best Wishes
