Multidim. Physics - Quantum Gravity - Early Cosmology

-------------------------------------------------------------------------------------------------------------------------------

Kaluza-Klein theories offer a scenario in which the gauge fields can be geometrized using the degrees of freedom available in a multidimensional metric. We concentrate our attention in providing a geometrization for the gauge connection too; the idea is to reproduce the right coupling between matter and gauge fields from a free multidimensional spinor Lagrangian. This approach has been successfully applied to the Electrodynamics and Electroweak models.
