Signatures of the $d^{*} (2380)$ hexaquark in d( $γ$ , $p n$ )

M. Bashkanov, D. P. Watts, S. J. D. Kay +74

We report a measurement of the spin polarisation of the recoiling neutron in deuterium photodisintegration, utilising a new large acceptance polarimeter within the Crystal Ball at…

New data on $γ p \to η p$ with polarized photons and protons and their implications for $N^{*} \to N η$ decays

J. Müller, J. Hartmann, M. Grüner +86

The polarization observables $T, E, P, H$ , and $G$ in photoproduction of $η$ mesons off protons are measured for photon energies from threshold to $W = 2400$ MeV ( $T$ ), 2280 MeV ($E…
