[G12] new secondary beam observation

[Hicks, Kenneth]

Hi John,

I see a similar peak for N-N scattering in my analysis.  As for the Lambda-N scattering, the hard part is to get the normalization correct.  It will take a lot more effort before it can be demonstrated that we get the correct N-N scattering cross section, and even more time before we can do something quantitative with any other particles.

    Hi all:
    
    It occurs to me that, if we can observe Lambda-proton elastic scattering
    in g12, we should also be able to see something easier like
    proton-proton scattering.  I looked over the data again, requiring only
    two protons in the final state, and plotted the missing mass in "X p -->
    p p".  The attached resulting plot has approximately 1.2 million events
    in the peak above background.
    
    We don't have a g12 meeting this week, but I thought y'all might like to
    see this.  My life is getting interesting...
