New Measurements of the Deuteron-to-Proton F 2 Structure-Function Ratio

F. A. Gonzalez, W. Henry, Alina Karki, C. Morean et autres

Nucleon structure functions, as measured in lepton-nucleon scattering, have historically provided a critical observable in the study of partonic dynamics within the nucleon. However, at very large parton momenta, it is both experimentally and theoretically challenging to extract parton distributions due to …

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

S. Alsalmi, I. Albayrak, A. Ahmidouch, J. Arrington et autres

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 scattering cross sections were measured in Jefferson Lab Experimental …

First Measurement of the EMC effect in B10 and B11

Alina Karki, D. Biswas, Fernando Álves González, William Henry et autres

The nuclear dependence of the inclusive inelastic electron scattering cross section (the EMC effect) has been measured for the first time in $^{10}\mathrm{B}$ and $^{11}\mathrm{B}$. Previous measurements of the EMC effect in $A\ensuremath{\le}12$ nuclei showed an unexpected nuclear dependence; $^{10}\mathrm{B}$ and $^{11}\mathrm{B}$ …

Constraints on the onset of color transparency from quasielastic C12(e,e′p) up to Q2=14.2(GeV/c)2

D. Bhetuwal, John C. Matter, Holly Szumila-Vance, C. Ayerbe Gayoso et autres

Quasielastic scattering on $^{12}\mathrm{C}(e,{e}^{\ensuremath{'}}p)$ was measured in Hall C at Jefferson Lab for spacelike four-momentum transfer squared ${Q}^{2}$ in the range of $8\text{--}14.2\phantom{\rule{0.222222em}{0ex}}{(\mathrm{GeV}/c)}^{2}$ with proton momenta up to $8.3\phantom{\rule{0.222222em}{0ex}}\mathrm{GeV}/c$. The experiment was carried out in the upgraded Hall C at Jefferson Lab. …
