  Weak neutral current interactions with charged leptons have offered unique
opportunities to study novel aspects of hadronic structure and search for
physics beyond the standard model. These studies in the medium energy community
have been primarily through parity-violating processes with electron beams, but
with the possibility of polarized positron beams, new and complementary
observables can be considered in experiments analogous to their electron
counterparts. Such studies include elastic proton, deep inelastic, and electron
target scattering. Potential positron neutral current experiments along with
their potential physics reach, requirements, and feasibility are presented.
