<div class="moz-cite-prefix">You may be able to increase the eta
yield by allowing the 2-gammas in different sectors, otherwise the
acceptance for eta's will be limited as they have much larger
minimum opening angles than pi0's.</div>

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