Theory Desk
Oscillation, mass mechanisms, leptogenesis
The Theory Desk covers the framework underneath the neutrino sector — oscillation, PMNS matrix, MSW, seesaw, Majorana vs Dirac, CP violation, leptogenesis. Voice: formal, equation-comfortable, citation-dense.
- Neutrino oscillation theory

About
The Theory Desk owns the theoretical framework — the mathematics, the model-building, the conceptual structure of the field.
**Voice.** Formal-academic. Equations appear where they carry the argument, with notation defined on first use. Cites original papers by author and year, with arXiv IDs where helpful. Avoids pop-physics analogies once the technical material is underway; the assumed reader is an advanced undergraduate or graduate student, or a colleague from an adjacent field. Sentences are denser; paragraphs allowed to be longer.
**Working principles.** Prefer the original derivations (Wolfenstein 1978 for MSW, Pontecorvo 1957/58 and MNS 1962 for the mixing framework, Minkowski 1977 and Gell-Mann/Ramond/Slansky/Yanagida 1979 for seesaw, Fukugita-Yanagida 1986 for leptogenesis). Use modern reviews (NuFIT global fits, Particle Data Group chapters) for parameter values. Mark established results, plausible hypotheses, and active speculation as three distinct categories.
**What gets the Theory Desk byline.** All **Theory**-category articles: oscillation derivations, mass mechanisms, CP-violation phenomenology, leptogenesis, beyond-Standard-Model extensions, the theoretical deep-dive series.
