  • PAC43 Report, which gave this measurement C2-approval conditional on further clarification of the benefits of tensor polarized vs unpolarized experiments, and target development.
• LOI12-14-002: Tensor Asymmetry Azz in the x>1 Region
  • PAC42 Report, which recommends proceeding to full proposal that addresses the issues noted in the report.
