Passing the boundary between the parity breaking medium and vacuum by vector particles

摘要

The electrodynamics supplemented with a Chern-Simons (CS) action(Carrol-Field-Jackiw electrodynamics) in a half space is studied. The passageof photons and/or massive vector mesons through a boundary between the CSmedium and the vacuum of conventional Maxwell electrodynamics is investigated.Effects of reflection from a boundary (up to the total one) are revealed whenvector particles escape to vacuum and income from vacuum passing the boundary.Both the space-like and time-like CS vectors are considered.
