Here is an abstract for the APS meeting (as we have discussed, I think that</div>

it would make sense to present JEF there). Please take a look.</div>

JLab Eta Factory experiment in Hall D
<div><br>
</div>
<div>The new experiment, JLab Eta Factory (JEF), in the experimental Hall-D at Jefferson Lab
</div>
<div>will extend the physics potential of the GlueX beyond the main spectroscopy program
</div>
<div>and study rare decays of eta mesons. Among various physics topics, the </div>
<div>experiment will focus on decays of eta mesons to the $\eta\to\pi^0\gamma\gamma$ final
</div>
<div>state. This decay mode provides an important information for higher-order calculations
</div>
<div>in chiral perturbation theory. The final state is ideal for the search of the leptophobic
</div>
<div>dark $B$ boson in the reactions $\eta\to\B\gamma$, $B\to\pi^0\gamma$ and </div>
<div>the scaler dark matter mediator $S$ in the channel $\eta\to\pi^0S$, $S\to\gamma\gamma$.
</div>
<div>The experiment requires to upgrade the inner part of the forward lead glass calorimeter of the GlueX detector with high-granularity, high-resolution lead tungstate $\rm PbWO_{\rm 4}$ scintillating crystals. The detector will be ready to take data in 2023.
I will give an overview of the JEF project.</div>
