Effective interaction of Chern-Simons boson with fermions
Ivan Hrynchak, Oleksandr Khasai, Yuliia Borysenkova +2
We consider a vector extension of the Standard Model (SM) with a Chern-Simons-type interaction. This extension introduces a new massive vector boson (the Chern-Simons (CS) boson) t…

Constraints on the neutrino extension of the Standard Model and baryon asymmetry of the Universe
Volodymyr Gorkavenko, Oleksandr Khasai, Oleg Ruchayskiy +1
Heavy neutral leptons (HNLs) can cause new effective interactions of Standard Model particles, particularly charged lepton flavour violation (cLFV) processes. The non-observation o…

Extension of the Standard Model with Chern-Simons type interaction
V. Gorkavenko, I. Hrynchak, O. Khasai +1
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-calle…
