Dark energy from gravitational corrections
  We study physics concerning the cosmological constant problem in the
framework of effective field theory and suggest that a dominant part of dark
energy can originate from gravitational corrections of vacuum energy, under the
assumption that the classical gravitational fields do not couple to a large
portion of the vacuum energy effectively, in spite of the coupling between
graviton and matters at a microscopic level. Our speculation is excellent with
terascale supersymmetry.
