Calculation record

Positive-energy Dirac projection and scalar/exchange chiral bridge.

Depth six is fixed. The exchange identity assumes normal-ordered fermionic
quantization and a Gaussian closure; an exact one-particle counterexample
prevents silently treating that closure as the written classical equation.

Research context

  • Master chiral current projection

    Positive-energy projection of a massive six-spatial-dimensional Dirac scalar current supplies the four-component polarization, Berry kinetic term, and a calculable momentum-transfer bivector source.

  • Master scalar exchange bridge

    A normal-ordered fermionic scalar interaction yields the auxiliary chiral polarization coefficient under Gaussian closure, while an exact one-particle counterexample fixes the limits of that bridge.
