Non-Diffractive Topological Spin Textures of Relativistic Twisted Fermion Beams

Andrei Afanasev, Carl E. Carlson

In optics and acoustics, in structured beams, non-diffracting polarization measures in clearly diffracting beams, and spin direction distributions in the core of these waves that h…

Semi-inclusive pion electroproduction at the highest transverse momenta

Andrei Afanasev, Carl E. Carlson

At the energies of present and future electron accelerators designed to study the structure of hadrons, there is a regime where hard pion electroproduction proceeds by a perturbati…

Contribution of Exchange in Elastic Muon-Proton Scattering

Atharva Naik, Andrei Afanasev

The effect of the lepton's mass is significantly enhanced when the beam's energy is on the order of the lepton's mass. In the case of electrons, this corresponds to beam momenta on…
