  In this work we present an update to a previous calculation of the
Next-to-Leading Order (NLO) corrections to the Vector Dark Matter (VDM) direct
detection cross section. The model under investigation is a minimal extension
of the Standard Model (SM) with one extra vector boson and one extra complex
scalar field, where the vector is the DM candidate. We have computed the
spin-independent cross section for the scattering of the VDM particle with a
nucleon. We now provide an update to the NLO cross section for the direct
detection of the DM particle. We further discuss the phenomenological
implications of the NLO corrections for the sensitivity of the direct detection
DM experiments.
