[G12] eta phi acceptance

[Mukesh Saini]

Hello,

I simulated Phi-Eta production for a photon with energy between 4.4-5.6 GeV. For a Phi-Eta resonance around 1680 MeV the acceptance was approximately 0.0035 or 0.35% for CLAS with g12 experimental geometry.

As for the estimated number of Phi-Eta events in the g12 data sample from my analysis, its ~1550 Phi's and Eta's that pass my Cuts. After I use Side-Band subtraction though it comes down to about 1000.

Mukesh.
