Dirac spinors and tachyon quantization
Bibliographic record
Abstract
Dirac spinors for spin-1/2 free tachyons are derived from the Dirac and Klein-Gordon equations in terms of the standard helicity representation of the Poincaré group and superluminal transformations (SLTs). It is shown that the proposed theory of second quantization is Lorentz invariant without inverting the spin-statistics relationship and without introducing indefinite pseudotachyonic states. Second quantized theory of spin-1/2 tachyons in the time-energy representation shows that tachyons are localized in time and that the most natural space for the description of tachyons is T4-space. It has been emphasized that on passing from R4-space (bradyons) to T4-space (tachyons) via either, i.e., complex or real SLTs, tachyons behave in T4-space exactly as bradyons do in R4-space. T4-space can be visualized as an internal space for a subluminal observer while R4-space appears as an internal space for a superluminal observer. PACS Nos.: 14.80K, 03.30t

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
