Probing Composite Structure and Spin-Orbit Coupling with GPDs in He
Antonio Garcia Vallejo, Matthew D. Sievert
In this work, we extend the Impulse Approximation for the generalized parton distributions (GPDs) of a spin-0 composite hadron with spin- constituents to manifestly i…

Solution of Relativistic Feshbach-Villars Spin-1/2 Equations
D. Wingard, A. Garcia Vallejo, Z. Papp
We propose method for studying relativistic spin- particles by solving the corresponding Feshbach-Villars equation. We have found that the Feshbach-Villars spin- equation…
