Neutrino Oscillations in Brans–Dicke Theory of Gravity
نویسندگان
چکیده
Flavor oscillations of neutrinos are analyzed in the framework of Brans–Dicke theory of gravity. We find a shift of quantum mechanical phase of neutrino proportional to GN∆m and depending on the parameter ω. Consequences on atmospheric, solar and astrophysical neutrinos are discussed.

Pauli (or Einstein) frame is used to study the Brans-Dicke gravity theory, minimally coupled with dilatonic Brans-Dicke scalar field, whose solutions involve degenerate metrics. Some of these solutions exhibit transitions from an Euclidean domain to a Lorentzian space-time corresponding to a spatially flat Robertson-Walker cosmology.
متن کاملFour-dimensional interior solutions from Jordan-Brans-Dicke Theory of Gravity.
We study spherically symmetric solutions to the Jordan-Brans-Dicke field equations under the assumption that the space-time may possess an arbitrary number of spatial dimensions. Assuming a perfect fluid with the equation of state p = ερ, we show that there are static interior nontrivial solutions in three dimensional Jordan-Brans-Dicke gravity theory.

متن کاملIllusions of general relativity in Brans–Dicke gravity
Contrary to common belief, the standard tenet of Brans–Dicke theory reducing to general relativity in the ω → ∞ limit is false when the trace of the matter energy–momentum tensor vanishes. The issue is clarified in a new approach using conformal transformations. The otherwise unaccountable limiting behavior of Brans–Dicke gravity is easily understood in terms of the conformal invariance of the ...
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.
