**The Higgs mode is a ubiquitous
collective excitation in relativistic systems with broken continuous symmetry.
It is expected to appear in antiferromagnets, short coherence length
superconductors, charge density waves, and superfluids near the Mott
transition. Detection of the mode is a valuable test of the
underlying field theory, and its mass gap is a measure of proximity to a
quantum critical point. However, since
the Higgs mode can decay into low energy Goldstone modes, its
experimental visibility has been questioned. I will show that
the visibility depends on the symmetry of the measured susceptibility.
Furthermore, I will show that the Higgs peak survives even in the
proximity of the strong coupling quantum critical point
in two dimensions.**
