GIFT v3.0 : Geometric Information Field Theory

The Standard Model of particle physics contains nineteen free parameters whose values are determined exclusively through experiment. These parameters, spanning six orders of magnitude from the electron mass to the top quark mass, lack any theoretical explanation within the Standard Model itself. This paper presents a geometric framework that derives these parameters from topological invariants of a seven-dimensional G2-holonomy manifold coupled to E8 x E8 gauge structure.

The construction employs the twisted connected sum method of Joyce and Kovalev, which builds compact G2 manifolds by gluing asymptotically cylindrical building blocks. For the specific manifold K7 considered here, this construction establishes Betti numbers b2 = 21 and b3 = 77 through Mayer-Vietoris exact sequences. These topological integers, together with the algebraic invariants of E8 (dimension 248, rank 8) and G2 (dimension 14), determine physical observables through cohomological mappings.

The framework contains no continuous adjustable parameters. All predictions derive from discrete structural choices: the gauge group E8 x E8, the specific K7 topology, and G2 holonomy. Within these constraints, the framework yields 18 predictions. The dimensionless predictions achieve mean deviation of 0.087% from experimental values, with four exact matches and several agreements below 0.01%.

The most significant prediction concerns the neutrino CP violation phase: delta_CP = 197 degrees. The DUNE experiment (2028-2030) will measure this quantity with precision of 5-10 degrees, providing a decisive test. A measurement outside the range 182-212 degrees would falsify the framework.

Whether these agreements reflect genuine geometric determination of physical parameters or represent elaborate numerical coincidences remains an open question that awaits peer-review.
