  We evaluate the elastic scattering cross section of vector dark matter with
nucleon based on the method of effective field theory. The dark matter is
assumed to behave as a vector particle under the Lorentz transformation and to
interact with colored particles including quarks in the Standard Model. After
formulating general formulae for the scattering cross sections, we apply them
to the case of the first Kaluza-Klein photon dark matter in the minimal
universal extra dimension model. The resultant cross sections are found to be
larger than those calculated in previous literature.
