This would be performed with an unpolarized electron beam and transversely polarized, spin-1, nuclear target. This structure function was first identified by Jaffe and Manohar in 1989 as \"a clear signature for exotic gluonic components in the target,\" and a recent lattice QCD result by our collaborators has prompted renewed interest in the topic.
