Quasi-free photoproduction of eta-mesons off 3He nuclei

L. Witthauer, D. Werthmueller, I. Keshelashvili +70

Quasi-free photoproduction of -mesons has been measured off nucleons bound in He nuclei for incident photon energies from the threshold region up to 1.4 GeV. The experiment…

An initial study of mesons and baryons containing strange quarks with GlueX

The GlueX Collaboration, A. AlekSejevs, S. Barkanova +97

The primary motivation of the GlueX experiment is to search for and ultimately study the pattern of gluonic excitations in the meson spectrum produced in collisions. Recent la…
