Parity Nonconserving Nuclear Interactions and Weak Neutral Currents

This is a review article on recent developments, of researches on the parity nonconserving nuclear interactions in connection with the weak neutral currents. Properties of the weak neutral currents clarified by high energy neutrino reactions are presented. Problems of the parity violating nucleon-meson vertices and of the parity nonconserving nuclear potentials are discussed. Dependences on inner parts of strong interaction potentials are argued. Parity nonconserving quantities are explicitly given in terms of the parity nonconserving weak interactions and discussed in details.
