Astrophysical limit on the coupling constant of hypothetical leptonic photons to leptons
PACS: 14.80.-j
The hypothetical leptonic photons, namely, those that have the coupling to electrons can be produced in the Sun and other star objects by the process of photoproduction. Being weakly interacting particles they could substantially influence the star evolution by changing the process of heat release. In order this not to happen the leptonic coupling constant should be smaller than ~ 10~2e i.e. much smaller than ~ 10-12 required by the stability of the bodies with respect to leptonic Coulomb forces.
