Probing the Brans-Dicke Gravitational Field by Cerenkov Radiation
نویسنده
چکیده
The possibility that a charged particle propagating in a gravitational field described by Brans-Dicke theory of gravity could emit Cerenkov radiation is explored. This process is kinematically allowed depending on parameters occurring in the theory. The Cerenkov effect disappears as the BD parameter ω → ∞, i.e. in the limit in which the Einstein theory is recovered, giving a signature to probe the validity of the Brans-Dicke theory.

Nonstatic global string in Brans-Dicke theory
Gravitational field of a nonstatic global string has been studied in the context of Brans-Dicke theory of gravity. Both the metric components and the BD scalar field are assumed to be nonseparable functions of time and space.The spacetime may or may not have any singularity at a finite distance from the string core but the singularity at a particular time always remains. It has been shown that ...
متن کاملVacuumless cosmic strings in Brans - Dicke theory
The gravitational fields of vacuumless global and gauge string have been studied in Brans-Dicke theory under the weak field assumption of the field equations. It has been shown that the global vacuumless string has a repulsive gravitational effect whereas the gauge string has an attractive gravitational effect in BD theory.
متن کاملRenormalization in quantum Brans-Dicke gravity
In the Brans-Dicke model we treat the scalar field exactly and expand the gravitational field in a power series. A comparison with 2D sigma models and φ perturbation theory in four dimensions suggests that the perturbation series in 4D Brans-Dicke model is renormalizable.
متن کاملGlobal Monopoles in Brans-Dicke Theory of Gravity
The gravitational field of a global monopole in the context of Brans-Dicke theory of gravity is investigated. The space-time and the scalar field generated by the monopole are obtained by solving the field equations in the weak field approximation. A comparison is made with the corresponding results predicted by General Relativity. Electronic address: [email protected] 1 Monopoles resulting ...

The spectra of relic gravitational waves produced as a result of cosmological expansion of the inflationary models are derived in Brans-Dicke (BD)theory of gravity.The time dependence of the very early Hubble parameter and matter energy density are derived from frequency dependent spectrum of relic gravitational waves.Also it is found that Brans-Dicke scalar field contributes to the energy dens...
