Propagators in the Correlated Worldline Theory of Quantum Gravity

Understand

Starting from a formulation of Correlated Worldline (CWL) theory in terms of functional integrals over paths, we define propagators for particles and matter fields in this theory.

• We show that the most natural formulation of CWL theory involves a rescaling of the generating functional for the theory; correlation functions then simplify, and all loops containing gravitons disappear from perturbative expansions.
• The spacetime metric obeys the Einstein equation, sourced by all of the interacting CWL paths.
• The matter paths are correlated by gravitation, thereby violating quantum mechanics for large masses.
