General analysis of polarization phenomena in $e^{+} + e^{-} \to N + N ˉ$ for axial parametrization of two--photon exchange

G. I. Gakh, E. Tomasi-Gustafsson

General properties of the differential cross section and of the polarization observables are derived for the $e^{+} + e^{-} \to N + N ˉ$ reaction, in presence of two--photon exchange. Po…

Asymptotic behavior of nucleon electromagnetic form factors in time-like region

E. Tomasi-Gustafsson, G. I. Gakh

We study the asymptotic behavior of the ratio of Pauli and Dirac electromagnetic nucleon form factors, $F_{2} / F_{1}$ , in time-like region for different parametrizations built for the s…

$Θ^{+}$ -pentaquark parity from associative baryon production in $π D$ collisions, $π^{\pm} + D \to Θ^{+} + Σ^{\pm}$

G. I. Gakh, A. P. Rekalo, E. Tomasi-Gustafsson

We derive, in model independent way, the spin structure of the matrix element for the reaction of associative $Θ^{+}$ pentaquark production, $π^{\pm} + D \to Θ^{+} + Σ^{\pm},$ in the thre…

Nucleon electromagnetic structure: past, present, and future

Egle Tomasi-Gustafsson

We present the experimental status of electromagnetic hadron form factors. New and surprising results, based on polarization measurements, have been recently obtained for the elect…
