摘要: We argue that, when coupled to Einstein's theory of gravity, the Yukawa may solve cosmological constant problem in following sense: The radiative corrections fermions generate an effective potential for scalar field, such that term Lambda_eff is dynamically driven zero. Thence, any initial positive Lambda_0, = 0 attractor semiclassical Einstein fermionic and matter fields. When negative, Lambda_eff=Lambda_0 does not change. Next we dark energy Universe be explained by a GUT scale fermion with mass, m 4.3 * 10^15 (Lambda_0/10^13GeV)^(1/2) GeV. Finally, comment on how inflationary paradigm, BEH mechanism phase transitions early get modified light our findings.
