[clas12_rgk] Isupov results: 2 gamma Invariant mass

[Viktor Mokeev]

Dear Colleagues,


Evgeny Isupov repeated selection of gvp p--->pi^0p'---> gamma gamma p' events from the same data set and with the same selection criteria as FX did. His results for 2gamm inv masses are consistent with FX.


 Best Regards,

                                      Victor

Hi Victor Ivanovich,

I used FX’s cuts and plotted 2 gamma invariant mass.
On the right you can see the same plot only in log scale,
we can clearly see the eta meson signal.
