Gravitational form factors (GFFs) offer profound insights into the spatial distribution of the strong force within hadrons and are intimately linked to the trace anomaly -- a key feature of QCD that underpins the proton’s finite mass and the pion’s near-zero mass. These fundamental observables will be accessible with high precision in upcoming electron-ion collider experiments. On the...
AFFINITY is a numerical tool that allows experimental data to be connected to the corresponding theoretical framework: collinear or TMD factorization, as appropriate. Recently the affinity tool has been modified and upgraded in such a way that event-by-event analyses can be performed, improving its reliability and precision. I will present our most recent results for JLab12 phase space...
During a ten-year tenure that began with a summer internship, and comes to an end as scientific staff, I had the opportunity to contribute directly and indirectly to nearly every aspect of the development of photoguns and Wien spin rotators at Jefferson Lab: from GaAs photocathode activation to high-voltage testing and beam delivery, and from conceptual sketches to a patented design. This talk...
An overview of electron beam deposition techniques and experiments conducted at Stony Brook University for PID Detectors. Namely, an emphasis on pfRICH (proximity focusing RICH detector) and the coating of high reflectivity mirrors for ePIC, as well as a novel R&D effort to redefine multi-wire drift chambers (MWDC) technology using coated carbon fiber wires.
The Proximity Focusing RICH (pfRICH) detector is a key sub-system fur particle identification (PID) at ePIC. It sits about 1.2 m from the interaction point in the electron-going direction, covering $-3.5 < \eta < -1.5$ in pseudorapidity and full $2\pi$ in azimuth. It will be primarily used for identification of scattered electrons from deep inelastic scattering (DIS) events, as well as for...
Transverse Momentum Dependent Parton Distribution Functions (TMDPDFs) provide crucial insights into the three-dimensional structure of hadrons and can be extracted from processes involving multiple kinematic scales, including Drell-Yan (DY), Semi-Inclusive Deep Inelastic Scattering (SIDIS), and $e^+e^-$ annihilation. Deep Neural Networks (DNNs) have emerged as powerful tools for information...
AstroPix is a high-voltage CMOS (HV-CMOS) monolithic silicon sensor and a key component of the Barrel Imaging Calorimeter (BIC) for the ePIC experiment, alongside the lead/scintillating-fiber (Pb/SciFi) sampling calorimeter. Interleaved within the calorimeter layers, AstroPix provides fine-grained shower imaging, enabling critical performance capabilities such as electron/pion or gamma/pion...
