  The CDF, ATLAS and LHCb have released the measurements on the W boson mass
$m_W$ at $\sqrt{S}=1.96, 7, 13 TeV$, respectively. The measured values show the
declining tendency, namely $m_W$ decreases with the increment of the collider
energy. If the declining tendency is confirmed, it might be the signal of
metric field at high energy colliders. In this paper, we propose a model to
account for such tendency and explore the properties of the model.
