摘要
A new physics scenario to explain PeV neutrinos observed in the IceCube experiment is introduced,with dark matter and dark energy considered.A slowly decaying very heavy fermion with a Pe V mass as the dark matter particle is the origin of the PeV neutrinos.They couple to an extremely light field and this light field constitutes the dark energy.
