Non-Metric Gravity I: Field Equations
What will the slim down versions of h-bar look on this side of the desert?
This is another great step.
This is an approach to keep your eye on.

Non-Metric Gravity I: Field Equations
Can it be done?As curvature has dimensions 1/L, L being length, such terms are dimensionless. To give them the dimension M�, M being mass, required from the action one has to multiply these terms by a dimensionfull parameter – the Planck constant ~. Thus, the terms in the quantum corrected action that are of second order in curvature have a multiple of ~ in front of them and thus are quantum corrections. This power of ~ agrees with the fact that these terms arise at one loop order of perturbation theory. Containing a prefactor of ~, these terms should be ignored when considering the classical gravity theory, as this is obtained via ~ → 0 limit.
