On a possible compensation of the QCD vacuum contribution to the Dark
Energy    [PDF]

Roman Pasechnik, Vitaly Beylin, Grigory Vereshkov

We demonstrate one of the possible ways to compensate the large negative quantum-topological QCD contribution to the vacuum energy density of the Universe by means of a positive constant contribution from a cosmological Yang-Mills field. An important role of the exact particular solution for the Yang-Mills field corresponding to the finite-time instantons is discussed.
