The emission of the Cerenkov radiation by charged particles is analyzed for stationary metrics. Results are applied to the Kerr geometry and the scalar-tensor theories of gravity. Particular emphasis is given to Brans-Dicke theory of gravity where the Cerenkov effect turns out to be kinematically allowed. It is related to the Brans-Dicke parameter ε, and vanishes in the limit in which general relativity is recovered (ε → ∞).

Abstract
The emission of the Cerenkov radiation by charged particles is analyzed for stationary metrics. Results are applied to the Kerr geometry and the scalar-tensor theories of gravity. Particular emphasis is given to Brans-Dicke theory of gravity where the Cerenkov effect turns out to be kinematically allowed. It is related to the Brans-Dicke parameter ε, and vanishes in the limit in which general relativity is recovered (ε → ∞).File in questo prodotto:
