  Local scale invariant theory leads to the existence of a new particle called
the Weyl vector meson. We study a generalized Standard Model, which displays
local scale invariance. The model contains a real scalar field, besides the
Higgs multiplet and coupling between the Higgs and Weyl meson. For certain
range of coupling parameters, the Weyl-Higgs coupling leads to interesting
phenomenon in particle colliders as well as in cosmology. Here we study the
signature of the Weyl meson in particle colliders and determine the range of
coupling parameters for which it can solve the dark matter problem.
