<span style="font-family: Aptos, sans-serif;">Dear all,</span><br>
<br>
<span style="font-family: Aptos, sans-serif;">I’m sharing the abstract I submitted for the APS Global Physics Summit 2026 for your feedback and suggestions. The abstract is attached below.</span></p>

<p class="MsoNormal" style="text-align: left; text-indent: 0px; margin: 0cm;"><span style="font-family: Aptos, sans-serif; font-size: 16px; color: black;">I would greatly appreciate any comments or recommendations for improvement before the abstract edit deadline (October
31).</span></p>

<span style="font-family: "Times New Roman", serif; font-size: 16px; color: black;">We report on preliminary studies of
</span><span style="font-family: "Times New Roman", serif; font-size: 16px; color: rgb(33, 33, 33);">coherent ö meson electroproduction off helium-4 nuclei<b> </b>using data from the recently run ALERT experiment at Jefferson Lab<b>.
</b>The experiment combines the large acceptance of the CLAS12 detector with the dedicated ALERT recoil detector, enabling detection of low-momentum nuclear fragments in coincidence with the scattered electron and produced mesons. Detector calibrations and
reconstruction algorithms are currently being finalized, and the first pass of analysis is underway. Preliminary analysis on the coherent ö production channel will be presented<b>,</b> representing an important step toward the extraction of gluonic distributions
in helium-4 nuclei through deeply virtual meson production, and providing new opportunities to explore the role of gluons in nuclear structure.</span></p>
