It provides a comprehensive review of vacuum Cherenkov radiation for modified fermions, highlighting the differences between spin-flip and non-spin-flip processes.

Findings

Decay rates for both process classes are summarized.

Distinct characteristics of the two process types are identified.

Implications for Lorentz violation detection are discussed.

Abstract

The current article reviews results on vacuum Cherenkov radiation obtained for modified fermions. Two classes of processes can occur that have completely distinct characteristics. The first one does not include a spin flip of the radiating fermion, whereas the second one does. A r\'{e}sum\'{e} will be given of the decay rates for these processes and their properties.
