A 3BF model of quantum gravity coupled to Standard Model matter
Pavle Stipsic, Marko Vojinovic
We develop an explicit model of quantum gravity coupled to the matter fields of the Standard Model, based on the 3-group structure and the 3BF action, within the framework of highe…
Correspondence between 3BF and Einstein-Cartan formulations of quantum gravity
Pavle Stipsic, Marko Vojinovic
We construct a correspondence between the quantized constrained 3BF theory and the quantized Einstein-Cartan theory with contact spin-spin interaction, both of which describe the S…
The 3BF theory as a TQFT
Tijana Radenkovic, Marko Vojinovic
We study the path integral quantization of the topological 3BF theory, whose gauge symmetry is described by a 3-group. This theory is relevant for the quantization of general relat…
Symmetry breaking mechanisms of the 3BF action for the Standard Model coupled to gravity
Pavle Stipsic, Marko Vojinovic
We study the details of the explicit and spontaneous symmetry breaking of the constrained 3BF action representing the Standard Model coupled to Einstein-Cartan gravity. First we di…
Operational verification of the existence of a spacetime manifold
Nikola Paunkovic, Marko Vojinovic
We argue that there exists an operational way to establish the observability of the notions of space and time. Specifically, we propose a theory-independent protocol for a gedanken…
