別の表記

• proto-photon

語源

proto- +‎ photon, from Ancient Greek πρῶτος ‎(prôtos) + φῶς ‎(phôs) + -ιος ‎(-ios).

名詞

protophoton ‎(複数形 protophotons)

1. (astronomy) A single low-energy detected photon from the cosmic background radiation as an extrapolation of data from a large ultralow frequency telescopic array.
   • Detecting separate protophotons, is an arduous computing conundrum of fine phase tuning, but we have to accept some statistical error.
2. (physics) (theoretical particle - very まれに use) An as-yet-undetected particle proposed to explain, among other things, the mechanisms of gravity.
   • An Alternative View of Nuclear Structure: Proto-photon sub-shells.[1]
   • Proto-photon sub-shells.[2]

名詞

proto-photon (複数形 proto-photons)

1. (physics, rare) A theoretical but not yet detected particle proposed to explain, among other things, the mechanisms of gravity; a gauge boson.
   • 1966, Michael M. Hare, Microcosm and macrocosm:

     Since the proto-photon has no charge, it does not seem likely that we could detect such "orbital" motion for the electron-photon system.

   • 2007, Acta Physica Polonica - Volume 38, Issues 5-6, page 2080:

     Notice that here we slightly deviate from traditional VMD-2 because we include a direct coupling between the pions and the proto-photon.

   • 2012, M. G. Bowler, Femtophysics: A Short Course on Particle Physics, →ISBN, page viii:

     It is shown how the assumption that a singlet gauge boson (a proto-photon) and the neutral member of a triplet W=t° are mixed leads to the identification of the couplings of the quarks and leptons to the neutral intermediate boson Z°.
