Heavy-ion collisions have reached energies high enough to melt the nucleus into its fundamental constituents, the quarks and gluons, making a Quark Gluon Plasma (QGP). In addition to creating the QGP, these collisions can transfer large momenta to a small subset of quarks and gluons (also known as partons), thus promoting these partons to a highly excited state, which will subsequently radiate...

Ultra-relativistic heavy-ions collisions performed at the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC) produce a de-confined state of quarks and gluons, called quark-gluon plasma (QGP). One of the primary goals of these collisions is to learn the properties of QGP, through the modifications it imparts on jets and photons. Jets are a collimated spray of particles...

3. Rare $\eta$ Decay Signal and Background Generation for JEF

The Jefferson Lab $\eta$ Factory (JEF) will start acquiring data in early 2025. The experiment aims to give insight into the connection between Dark Matter physics models and the Standard Model by investigating rare decay processes of $\eta$ and ${\eta }^{\prime }$ mesons. Several other physics motivations are also a key factor of the experiment, such as probing $C$ and/or $P$ violation and aspects of...

Fermilab's 2023 measurement of the muon's anomalous magnetic moment ($a_{\mu }=(g-2{)}_{\mu }/2$) has heightened the discrepancy between experimental results and Standard Model predictions to $5.0\sigma$. By employing the structure of finite-energy QCD sum rules (FESR) and H\"older inequalities, the hadronic vacuum polarization (HVP) contribution to the leading order (LO) muon $g-2$ anomaly...

9. From Spin to Structure: Beam Spin Asymmetry in Exclusive Pion Electroproduction

Contributed Oral

The KaonLT/PionLT Collaboration probes hadron structure by measuring deep exclusive meson production reactions at Jefferson Lab. A set of high momentum, high resolution spectrometers in Hall C allow for precision measurements from which form factors and other observables can be extracted. One possible measurement is the beam spin asymmetry, which allows for the extraction of a polarized...

Generalized Parton Distributions (GPDs) are a huge advancement in our understanding of hadronic structure and non-perturbative QCD. To study GPDs, one may use the Deep Exclusive Meson Production (DEMP) reaction, but first one must find the Q^2 regime where DEMP is factorizable. The factorization regime is where the cross-section can be divided into two parts, a hard part calculated with pQCD,...
