Weyl meson and its implications in collider physics and cosmology

Abstract

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.
