Measurement of double-polarization asymmetries in the quasi-elastic $^3\vec{\mathrm{He}}(\vec{\mathrm{e}},\mathrm{e}'\mathrm{d})$ process
Abstract
We present a precise measurement of double-polarization asymmetries in the reaction. This particular process is a uniquely sensitive probe of hadron dynamics in and the structure of the underlying electromagnetic currents. The measurements have been performed in and around quasi-elastic kinematics at for missing momenta up to . The asymmetries are in fair agreement with the state-of-the-art calculations in terms of their functional dependencies on and , but are systematically offset. Beyond the region of the quasi-elastic peak, the discrepancies become even more pronounced. Thus, our measurements have been able to reveal deficiencies in the most sophisticated calculations of the three-body nuclear system, and indicate that further refinement in the treatment of their two- and/or three-body dynamics is required.
