Welcome and introductions to the Early Career & Photonuclear workshop.
I will present a history of the US national lab system from the Manhattan project to today.
One of the foremost goals of research into Quantum Chromodynamics
(QCD) is to quantify the internal structure of the proton from
first principles. Ab initio calculations of QCD matrix elements
like transverse momentum distributions (TMDs) using lattice QCD
are an essential part of achieving that goal. I present first
explorations of effects on TMDs induced by the more intricate
color...
This talk will discuss how (and how not) to present data, including some amazingly good (and amazingly bad) examples. It was inspired by Edward Tufte (“The Visual Display of Quantitative Information”) and some truly terrible physics talks.
I will discuss Short Range Correlations (SRCs) in the Nucleus.
In my talk, I will give an overview of the experiments at Jefferson Lab's experiment hall B with the CLAS12 and ALERT detector which allows to measure low energy recoils from electron interactions with a He-4 target.
The detection of d, t and He-3 remnants from He-4 gives an opportunity to unique experiments for tagged measurements of the EMC effect, of DVCS on light nuclei and of...
The Muon g-2 Experiment at Fermilab is on track to measure the muon magnetic anomaly to better than 140 parts-per-billion (ppb), an unprecedented level of precision. The muon's magnetic anomaly is sensitivity to all sectors of the Standard Model (SM), and thus provides a stringent test of the SM's completeness. The Muon g-2 Collaboration published its most recent result last summer (August...
One of the future upgrade scenarios proposed for Jefferson Lab is the addition of a positron beam capabilities. Positron scattering from hadronic targets can provide new information that cannot be accessed from electron scattering alone. Asymmetries between electron- and positron-scattering can isolate interference effects, such as those between deeply virtual Compton scattering and the...
Two photon exchange is one possible explanation for the disparity in the proton form factor ratio when comparing results from Rosenbluth scattering and polarization transfer experiments. To measure the effect of two photon exchange alone we intend to compare the different scattering asymmetries for electrons and positrons scattering off a polarized proton target. The asymmetry difference in...
Presenting preliminary measurements of pion fragmentation functions
Advice and suggestions in seeking postdoctoral and entry-level faculty positions in US academic institutions from the point of view of a long-time chair and PI and with supplemental advice and suggestions gleaned from a recent presentation of someone who has more recently gone through the process.
Short Range Correlations (SRCs) are a feature of the internal structure of all types of nuclei. SRC pairs have been well-studied with quasi-elastic electron scattering experiments. These experiments have suggested that that SRCs can be characterized by high relative momentum and low center of mass momentum. This reliance on electron scattering, however, makes it difficult to assess the...
Recent experiments at JINR and GSI aim at studying long- and short-range nuclear structure in inverse kinematic experiments with nuclear beams at few GeV/c/u. I will discuss preliminary results.
The A1n, d2n, GEn-II and A_LL experiments at Jefferson lab utilized a high luminosity polarized He3 target for precise measurements at high x and/or Q^2 settings. The target consists of a pumping chamber (where polarization of He3 takes place), a target chamber (where e- beam interacts with the target material) and transfer tubes (which facilitate a convective flow of the polarized material)....
Experiment E12-19-003, carried out in Jefferson Lab's Hall D in 2021, aimed to explore the predicted QCD phenomenon known as Color Transparency in photons, mesons, and baryons. The experiment used low atomic mass nuclei such as helium, deuterium, and carbon targets through photoproduction. In my discussion, I will present the preliminary cross-section ratio of the ρ0 meson between the targets...
The GlueX experiment has produced the world’s largest data sample for peripheral photoproduction of mesons with a goal to expand our understanding of the strong interaction and search for hybrid mesons. The data set was obtained at the Thomas Jefferson National Accelerator Facility utilizing the GlueX detector and a tagged linearly polarized photon beam that peaks between 8 - 9 GeV incident on...
The installation of a new lead tungstate calorimeter (ECAL) insert in Hall D’s GlueX detector at Jefferson Lab (JLab) will allow for the improved reconstruction of η/η’ decay channels. The ECAL is necessary for the upcoming Jefferson Lab Eta Factory (JEF) experiment, which aims to study rare decays of eta mesons. The insert consists of 1596 lead tungstate scintillating crystals which have been...
