Title: Measurements of Single and Pair Production of Hadrons in Nuclear SIDIS in the CLAS Experiment
Abstract: I will present recent measurements of semi-inclusive deep-inelastic scattering measurements off nuclei with CLAS, in both single-hadron and double-hadron channels. I will describe how these measurements can constrain the interaction between quarks and cold nuclear matter, and also the nuclear modifications to transverse-momentum dependent parton-distribution functions. I will finalize by describing an upcoming eA...
Title: Generalized Parton Distributions Through Universal Moment Parameterization: The Gluonic Sector with Deeply Virtual J/ψ Production
Abstract: We present a further step toward a global extraction of gluon generalized parton distributions (GPDs). In our previous work we performed the first global analysis of quark GPDs by including lattice quantum chromodynamics (QCD) calculations, global fitted forward parton distribution functions (PDFs), form factors (FFs), and Deeply Virtual Compton Scattering (DVCS) measurements from...
Title: Functionalizing Advanced Materials and Surfaces in Superconducting RF
Speaker: Zeming Sun (Cornell University)
Abstract: Materials scientists seek to contribute to the development of next-generation SRF accelerating cavities. In this seminar, I present recent achievements and learnings in designing advanced SRF materials and surfaces, including Nb3Sn [1,2], ZrNb(CO) [3,4], and Au/Nb surface design [5,6]. Efforts involve electrochemical synthesis, phase transformation, and surface chemistry, which are closely coupled with superconducting properties, SRF...

Topic: They Scatter Neutrinos, Don’t They?
Abstract: Despite the crushing difficulty of using neutrinos as a probe, neutrino scattering experiments in the US and Japan have recently benefited from ever more intense neutrino beams, new schemes for building cost-effective, large, capable detectors, and dogged determination to run long enough to complete a thousand marathons. I’ll discuss recent some results and techniques, with a focus on the MINERvA experiment at Fermilab.
As a child, Aldaisia “Daisy” Donald didn’t need to look far to find her inspiration.
“My dad is a retired lieutenant colonel in the Army, and I’ve always been a daddy’s girl,” said Donald, a radiation control technologist at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility and nine-year U.S. Navy veteran. “Growing up, he would always be gone on deployments, and when he came home, I remembered thinking, ‘He’s a hero.’ I always wanted to be like him.”
One of the U.S. Marine Corps’ 11 leadership principles stands out the most to Davis Wright, a user-support technician II at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility.
“Know yourself and seek self-improvement.”
As a high-school senior in 2011, he knew he wanted to find that wisdom.

Title: High-Energy Behavior of Quark Non-Local Operator: Implications for Lattice Calculations
Abstract: Pseudo and quasi-PDFs are key tools to compute parton distribution functions (PDFs) directly on the lattice. However, using the lattice to make these calculations has its challenges. To get the Bjorken-x dependence from the...
