The QGT:IR Particle Model: Vacuum Solitons, Spectral Resonance and the Physical Origin of Matter

The Standard Model of particle physics successfully predicts experimental outcomes,
yet it relies on the idealization of elementary particles as point-like entities, leading to
ultraviolet divergences and the need for renormalization. Moreover, key properties such as
mass, charge, and spin are introduced axiomatically rather than derived from underlying
physical mechanisms.
In this work, we develop a particle model within the framework of Quantum Gravity
based on Inverted Relativity (QGT:IR), in which spacetime is fundamentally Minkowskian
and the vacuum is treated as a physical medium. Elementary particles are reinterpreted
as finite-energy, non-linear solitonic excitations of a scalar vacuum field. The stability,
quantization, and observed properties of particles arise from spectral equilibrium, topological
protection, and resonant coupling with the vacuum.
This article establishes the conceptual and theoretical foundations of the QGT:IR Parti-
cle Model, demonstrating its internal consistency, compatibility with effective quantum field
theories, and empirical falsifiability.
