Searching for Gravity Without a Metric
Lukas W. Lindwasser, E. T. Tomboulis
Recently it has been explicitly shown how a theory with global coordinate (affine) invariance which is spontaneously broken down to its Lorentz subgroup will hav…
Multigravity and the cosmological constant
E. T. Tomboulis
The possibility of flat metric solutions in the presence of arbitrary, in particular, Planck mass sized cosmological constants is investigated within multigravity theory, the ghost…
Wavelet field decomposition and UV `opaqueness'
E. T. Tomboulis
A large body of work over several decades indicates that, in the presence of gravitational interactions, there is loss of localization resolution within a fundamental ( Plan…
Nonlocal vertices and analyticity: Landau equations and general Cutkosky rule
Paokuan Chin, E. T. Tomboulis
We study the analyticity properties of amplitudes in theories with nonlocal vertices of the type occurring in string field theory and a wide class of nonlocal field theory models.…
On the `simple' form of the gravitational action and the self-interacting graviton
E. T. Tomboulis
The so-called -form of the gravitational Lagrangian, long known to provide its most compact expression as well as the most efficient generation of the graviton vertices, is tak…
Causality and Unitarity via the Tree-Loop Duality Relation
E. T. Tomboulis
The tree-loop duality relation is used as a starting point to derive the constraints of causality and unitarity. Specifically, the Bogoliubov causality condition is ab initio deriv…
