Double Higgs mechanisms, supermassive stable particles and the vacuum energy

In the present work, a hidden scenario which cast a long-lived superheavy particle A0 and simultaneously an extremely light particle a with mass ma ∼ 10?32-10?33 eV is presented. The potential energy V (a) of the particle a models the vacuum energy density of the universe ?c 10?47 GeV4. On the other...

description In the present work, a hidden scenario which cast a long-lived superheavy particle A0 and simultaneously an extremely light particle a with mass ma ∼ 10?32-10?33 eV is presented.
