Restated Dynamics for Particles and Fields in a 5-D Framework: > Solution of the q/m problem |
|
Abstract |
In this work we present a revised approach to the problem of matter in the framework of the 5D compactified Kaluza-Klein model. We introduce a 5D external matter tensor and perform a simultaneous reduction of matter and geometry, facing the test-particle motion via an appropriate multipole expansion. Within this scheme the q/m puzzle is solved and the tower of huge massive modes is removed, without giving up with the compactification hypothesis. The model looks like a consistent modified gravity theory, where an extra scalar source term appears. Interesting scenarios and perspectives related to dark energy are discussed. |
