Again on hidden sector of the Universe, accessible through photonic portal

Understand

We describe more precisely the mechanism of spontaneous mass generation in the previously proposed model of hidden sector of the Universe.

• The hidden sector is conjectured to consist of sterile spin-1/2 fermions (sterinos) whose mass is spontaneously generated by sterile scalar bosons (sterons), while their interactions are mediated by sterile antisymmetric-tensor bosons (A bosons).
• Such a sector communicates with the familiar Standard Model sector through a photonic portal acting weakly between both sectors (but stronger than the universal gravity).
• This is due to photons which, beside sterinos and sterons, contribute to the source of the A bosons.
