Please join us for the 2019 Jefferson Lab Users Organization Annual Meeting, June 24-26. Registration is now open.
The theme of this year's program is "JLab Science Around the World.” Each day has a sub-theme, and these are: “an international user community,” “reaching the full potential of 12 GeV,” and “from 12 GeV to the EIC - toward CD-0,” setting the emphasis for each day.
The program includes a variety of physics talks, presentations from the User Group Board, laboratory management and funding agencies, and the winners of the thesis prize and the postdoc prize. Examples...
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...
