We present the description of the structure of light-nuclei (H2, H3, He3 and He4) in impulse approximation within the Light-Front approach [1,2], retaining nucleonic dof, only. In particular, the latter has been applied to investigate the reaction mechanism of polarized and unpolarized deep inelastic scattering (DIS) on nuclear targets, in the valence region and in the Bjorken limit [3,4,5]....
Much has been learned about 2N short-range correlations in JLab's 6 and 12 GeV eras, with more still coming up. However, a successful observation of 3N SRCs still eludes us. Based on predictions, the current kinematic reach at JLab is right on the edge of where 3N SRCs should start to dominate and an observation is possible, but not inevitable. We will discuss planned and soon to be...
The deuteron is a spin-1 system, and its tensor properties continue to be elusive in experimental measurements due to the complexity of the polarized target. Recently, there has been an increase in interest in the physics of the tensor components of this system due to advances in target technology. This talk will discuss the implications of studying semi-inclusive deep inelastic scattering...
The microscopic origin of the EMC effect remains a mystery, with new observables proposed in recent years to elucidate its origin including measurements of the spin and flavor dependence of the EMC effect, the A dependence in light nuclei, and tagged measurements of DIS in the deuteron. A new possibility, enabled by a JLab energy upgrade, would maintain the clean interpretation of the...
Searching for the onset of Color Transparency (CT) is a vibrant experimental effort to observe hadrons in a small color-neutral transverse size configuration in the nucleus. The observation of the onset of CT lies at the intersections between the quark-gluon degrees of freedom and the nucleonic descriptions of nuclei. CT is fundamentally predicted by perturbative quantum chromodynamics and is...
The main focus of the Jefferson Lab physics program of 6 GeV and 12 GeV era, which are now proposed to be extended here to 22 GeV, is to determine the mechanisms of confinement in hadron formation. A significant amount of information has been collected on understanding confinement through hadron spectroscopy. Another approach was introduced through the string-breaking mechanism studied via...
Decades after the discovery of the European Muon Collaboration (EMC) effect, theorists and experimentalists are still working to unravel its origin and deploy new methods to understand the in-medium modifications of nucleon structure. One novel way to probe the EMC effect is to study the fundamental structure of light nuclei, such as ²H and ⁴He, via the deeply virtual Compton scattering (DVCS)...
In this talk I will discuss the physics opportunities of studying quark structures w/ 22GeV electrons scattering off nuclei, mainly focusing on investigation of the unpolarized EMC effect, anti-shadowing effect, the 3D nuclear structure and other dynamics nuclear medium effects.
An upgrade of CEBAF at Jefferson Lab to around 22 GeV will open up key science that is not possible to access at 12 GeV. One kinematic regime where this is most possible is in the "middle" Bjorken x regime around 0.1, where the available momentum transfers at 12 GeV have limited or precluded several exciting measurements. Here, the long-standing mystery of anti-shadowing may now be probed for...
