π0 photoproduction on the proton for photon energies from 0.675 to 2.875 GeV

M. Dugger, B. G. Ritchie, J. P. Ball, P. Collins et autres

Differential cross sections for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}p{\ensuremath{\pi}}^{0}$ have been measured with the CEBAF Large Acceptance Spectrometer (CLAS) and a tagged photon beam with energies from 0.675 to 2.875 GeV. The results reported here possess greater accuracy in the absolute normalization than previous …

Measurement of Two- and Three-Nucleon Short-Range Correlation Probabilities in Nuclei

K. S. Egiyan, Natalya Dashyan, Misak M. Sargsian, Mark I. Strikman et autres

The ratios of inclusive electron scattering cross sections of 4He, 12C, and 56Fe to 3He have been measured at 1 < xB <. At Q2 > 1.4 GeV2, the ratios exhibit two separate plateaus, at 1.5 < xB < 2 and at …

η′ Photoproduction on the Proton for Photon Energies from 1.527 to 2.227 GeV

M. Dugger, J. P. Ball, P. Collins, E. Pasyuk et autres

Differential cross sections for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}p$ have been measured with the CLAS spectrometer and a tagged photon beam with energies from 1.527 to 2.227 GeV. The results reported here possess much greater accuracy than previous measurements. Analyses of these data suggest …

Measurement of the polarized structure function σLT' for pion electroproduction in the Roper-resonance region

K. Joo, L. C. Smith, I. G. Aznauryan, V. D. Burkert et autres

The polarized longitudinal-transverse structure function ${\ensuremath{\sigma}}_{{\mathit{LT}}^{'}}$ measures the interference between real and imaginary amplitudes in pion electroproduction and can be used to probe the coupling between resonant and nonresonant processes. We report new measurements of ${\ensuremath{\sigma}}_{{\mathit{LT}}^{'}}$ in the $N(1440){\frac{1}{2}}^{+}$ (Roper) resonance region …

Observation of nuclear scaling in the A(e,e′) reaction at xB>1

K. S. Egiyan, N. Dashyan, Misak M. Sargsian, S. S. Stepanyan et autres

The ratios of inclusive electron scattering cross sections of ${}^{4}\mathrm{He},$ ${}^{12}\mathrm{C},$ and ${}^{56}\mathrm{Fe}$ to ${}^{3}\mathrm{He}$ have been measured for the first time. It is shown that these ratios are independent of ${x}_{B}$ at ${Q}^{2}>1.4{\mathrm{GeV}}^{2}$ for ${x}_{B}>1.5,$ where the inclusive cross section depends …

Radiative corrections to electron-proton scattering

L. C. Maximon, J. A. Tjon

The radiative corrections to elastic electron-proton scattering are analyzed in a hadronic model including the finite size of the nucleon. For initial electron energies above 8 GeV and large scattering angles, the proton vertex correction in this model increases by at least …

High-accuracy comparison of electron and positron scattering from nuclei

Vincent Breton, P. Bricault, Lawrence S. Cardman, B. Frois et autres

We compare the elastic-scattering cross sections for electrons and positrons from $^{208}\mathrm{Pb}$ and $^{12}\mathrm{C}$. The results demonstrate that the electron-nucleus interaction can be described to good accuracy as a single hard-photon exchange process, and validate the theoretical framework used to interpret electron-scattering …
