Abstract

Extension of the Standard Model with Chern-Simons type interaction contains a new vector massive boson (Chern-Simons boson) that couples to electroweak gauge bosons by the so-called effective Chern-Simons interaction. There is no direct interaction between the Chern-Simons bosons and SM fermions. We consider existing restrictions on the parameters of this SM extension, the effective loop interaction of a new vector boson with SM fermions, and the possibility of the manifestation of the long-lived GeV-scale Chern-Simons bosons in collider experiments.
