We renew our intent to submit a proposal to perform a search for a non-zero value of the unmeasured hadronic double helicity flip structure function Δ(x,Q2), predicted to be sensitive to gluons in the nucleus. 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. An inclusive search with deep inelastic scattering, below x of 0.3, via single spin tensor asymmetries may be feasible using the CEBAF 12 GeV electron beam and JLab/UVa solid polarized target, and would represent the first experimental exploration of this quantity.
