We report a new measurement of the beam-spin asymmetry $\boldsymbol{\Sigma}$ for the $\vec{\gamma} n \rightarrow K^+\Sigma^-$ reaction using quasi-free neutrons in a liquid-deuterium target. The new dataset includes data at previously unmeasured phot

Determination of the polarization observables $C_{x}$, $C_{z}$, and $P$ for the $\vec{\gamma}d\to K^{0}\Lambda(p)$ reaction

Autor: Gleason, Colin, Ilieva, Yordanka

Many excited nucleon states ($N^{*}$s) predicted by quark models, but not observed in $\pi N$ channels, are expected to couple strongly to kaon--hyperon ($KY$) channels. While in the last decade data have been published for $KY$ photoproduction off t

We report the first extraction of the pion-nucleon multipoles near the production threshold for the $n\pi^+$ channel at relatively high momentum transfer ($Q^2$ up to 4.2 $\rm{GeV^2}$). The dominance of the s-wave transverse multipole ($E_{0+}$), exp
