Nucleosynthesis constraints on an extended Jordan-Brans-Dicke theory.

چکیده
In a natural extension of the Jordan{Brans{Dicke theory the scalar eld can couple much more strongly to dark than to visible matter. New limits on the coupling constants of the model are obtained from standard big{bang nucleosynthesis.

Properties of the static, spherically symmetric solutions in the Jordan, Brans-Dicke theory. ABSTRACT. We have studied the properties of the static, spherically symmetric solution of Jordan, Brans-Dicke theory. An exact interior solution for standard space-time line element in the Schwarzschild form is obtained.
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 کاملBrans-Dicke theory: Jordan vs Einstein Frame
It is well known that, in contrast to general relativity, there are two conformally related frames, the Jordan frame and the Einstein frame, in which the Brans-Dicke theory, a prototype of generic scalar-tensor theory, can be formulated. There is a long standing debate on the physical equivalence of the formulations in these two different frames. It is shown here that gravitational deflection o...
متن کاملEinstein-Brans-Dicke Cosmology
We studied the Einstein-Brans-Dicke cosmology in detail. The difference of the evolution of the universe is significant between Einstein-Brans-Dicke cosmology and standard big-bang model during the radiation-dominated era. The power-law evolution of the scale factor is fast enough to solve the cosmological puzzles and slow enough to avoid the graceful exit problem. However, the constraints from...
