摘要：We outline a fully relativistic formalism for describing neutrino-induced D-mediated single-pion
production in nuclei. To describe the nucleus, we turn to a relativistic plane-wave impulse approximation
(RPWIA) using realistic bound-state wave functions derived in the Hartree approximation
to the s -w Walecka model. Medium modifications of the D mass and width are accounted for
within a scheme that gives good results in photo-induced two-nucleon knockout reactions. As an
application, we present D-mediated one-pion production calculations for the typical MiniBooNE
kinematics. It is found that medium modifications roughly halve the RPWIA cross sections. The
model presented in this work can be naturally extended to include the effect of final-state interactions
in a relativistic and quantum-mechanical way.
