<p>Dear Izzy,</p>
<p>Nice abstract. I would support Axel's suggestion as well and propose a simple title such as:</p>
<p><i>η electroproduction at CLAS12</i></p>
<p>All the best</p>

Dear RG-K Group and HSWG Members,

<div dir="auto">
I hope this email finds you well. I'm writing to follow up on my previous communication regarding the abstract submission for the DNP.
<br>
<br>

Following feedback and adhering to the APS DNP guidelines, I have revised the abstract to meet the 1300 character limit. Please find the updated abstract below:

The exploration of nucleon structure and electromagnetic transitions from ground state to excited state is a cornerstone of nuclear physics research. Meson electro-production experiments have opened new avenues for investigating these phenomena, particularly in the 12 GeV era at Jefferson Lab with the CLAS12 spectrometer. The ηN final states, accessible only via isospin I = 1/2 resonances, provide a unique tool for studying nucleon excitations. By simplifying the analysis and enabling a cleaner extraction of resonance properties compared to the extensively studied πN final states, η electro-production offers a complementary approach. This work presents the first-ever measurement of the beam spin asymmetry (ALU) in exclusive η electroproduction, covering a previously unexplored kinematic region with 1.6 ≤ W ≤ 2.2 GeV. ALU is determined from the CLAS12 data using an analysis framework that considers the statistical limitations of the data set. Results are compared to theoretical models Jülich-Bonn-Washington and EtaMAID. ALU exhibits discrepancies with model predictions, highlighting the potential for refining theoretical descriptions of nucleon resonances and their electromagnetic couplings. These new results in a previously unmeasured kinematic region provide valuable input for future theoretical developments.

Dear RG-K Group and HSWG Members,
<br>
<br>
I hope this email finds you well.
<br>
<br>
I have been encouraged by RG-K group to submit an abstract for the upcoming DNP October 7-10. The abstract is identical to the one I presented at the PWA/ATHOS conference in May, which has already been previously circulated to the HSWG.
<br>
<br>
For your convenience, I have copied the abstract again down below. The abstract submission deadline is 8 July 2024.
<br>
<br>
I would appreciate any feedback or suggestions you may have regarding the abstract.
<br>
<br>
Thank you and all the best,
<br>

Exclusive $\eta$ Electro-Production Beam Spin Asymmetry Measurements using CLAS12 at Jefferson Lab
<br>
<br>
The exploration of nucleon structure and electromagnetic transitions from ground state to excited state is a cornerstone of nuclear physics research. Meson electro-production experiments have opened new avenues for investigating these phenomena, particularly in the 12 GeV era at Jefferson Lab with the CLAS12 spectrometer. The $\eta N$ final states, accessible only through isospin $I = 1/2$ resonances, provide a unique tool for studying nucleon excitations. By simplifying the analysis and enabling a cleaner extraction of resonance properties compared to the extensively studied $\pi N$ final states, $\eta$ electro-production offers a complementary approach to unraveling the structure of excited nucleons. This work presents the first-ever measurement of the beam spin asymmetry (BSA) in exclusive $\eta$ electro-production, covering a previously unexplored kinematic region with $1.6 \leq W \leq 2.2$ GeV. The BSA is extracted from the CLAS12 data using a comprehensive analysis framework that carefully considers the statistical limitations of the data set. The results are compared to predictions from theoretical models, such as the J"{u}lich-Bonn-Washington (JBW) and MAID, as well as compared to previously published cross-section and spin observable results from CLAS, and SLAC. Notably, the extracted BSA exhibits discrepancies with the model predictions, highlighting the potential for refining theoretical descriptions of nucleon resonances and their electromagnetic couplings through the incorporation of these new data. The high-precision data obtained in this previously unmeasured kinematic region now serve as valuable input for theorists to refine their models.
