Description
The Strong CP Problem can be resolved by introducing an additional global symmetry known as Peccei-Quinn symmetry.
Once PQ symmetry is broken the associated particle, the QCD axion, is a plausible dark matter candidate.
Calculating the cosmological energy density of the axion requires nonperturbative QCD input---the high-temperature topological susceptibility.
I will show results from a pure-glue calculation and examine the implications for the axion mass and coupling.
