Investigation of Medium Modifications to $^{12}$C Structure Functions in the Resonance Region Open

S. Alsalmi, I. Albayrak, A. Ahmidouch, J. Arrington, A. Asaturyan , et al. · 2025

We present results from a high precision experimental study of the nuclear modification of the longitudinal ($F_L$) to transverse ($F_1$) structure function ratio for bound nucleons in the resonance region. The inclusive electron scatterin…

Spin asymmetries for confined Dirac particles Open

Mark Paris, V. R. Pandharipande, I. Sick · 2018

We study the Bjorken x (or equivalently Nachtmann {xi}) dependence of the virtual photon spin asymmetry in polarized deep inelastic scattering of electrons from hadrons. We use an exactly solved relativistic potential model of the hadron, …

Proton Charge Radius from Electron Scattering Open

I. Sick · 2017

The rms-radius R of the proton charge distribution is a fundamental quantity needed for precision physics. This radius, traditionally determined from elastic electron-proton scattering via the slope of the Sachs form factor G e ( q 2 ) ext…

Reexamination of proton rms radii from low- power expansions Open

I. Sick, D. Trautmann · 2017

Several recent publications claim that the proton charge {\\em rms}-radius\nresulting from the analysis of electron scattering data restricted to {\\em low}\nmomentum transfer agrees with the radius determined from muonic hydrogen, in\ncon…

Form factors and radii of light nuclei Open

I. Sick · 2015

We discuss the determination of electromagnetic form factors from the {\em world} data on electron-nucleus scattering for nuclei $Z \leq 3$, with particular emphasis on the derivation of the moments required for comparison with measurement…

Evaluation of the proton charge radius from e-p scattering Open

J. Arrington, I. Sick · 2015

In light of the proton radius puzzle, the discrepancy between measurements of the proton charge radius from muonic hydrogen and those from electronic hydrogen and electron-proton scattering measurements, we reexamine the charge radius extr…
