Diquark Correlations from Nucleon Charge Radii
Carl E. Carlson, Christopher D. Carone, Herry J. Kwee +1
We argue that precise measurements of charge and magnetic radii can meaningfully constrain diquark models of the nucleon. We construct properly symmetrized, nonrelativistic three-q…
New experimental constraints on polarizability corrections to hydrogen hyperfine structure
Vahagn Nazaryan, Carl E. Carlson, Keith A. Griffioen
We present a state-of-the-art evaluation of the polarizability corrections--the inelastic nucleon corrections--to the hydrogen ground-state hyperfine splitting using analytic fits…
Two-Photon-Exchange Correction to Parity-Violating Elastic Electron-Proton Scattering
Andrei V. Afanasev, Carl E. Carlson
Higher-order QED effects play an important role in precision measurements of nucleon elastic form factors in electron scattering. Here we introduce a two-photon exchange QED correc…
The two-photon exchange contribution to elastic electron-nucleon scattering at large momentum transfer
Andrei V. Afanasev, Stanley J. Brodsky, Carl E. Carlson +2
We estimate the two-photon exchange contribution to elastic electron-proton scattering at large momentum transfer by using a quark-parton representation of virtual Compton scatteri…
