First I will review the QCD theta problem and the Peccei-Quinn
solution, with its new particle, the axion. I will review the
possibility of the axion as dark matter. If PQ symmetry was restored
at some point in the hot early Universe, it should be possible to make
a definite prediction for the axion mass if it constitutes the Dark
Matter. I will describe progress on one issue needed to mak

In our recent study of 2-flavor lattice QCD using chiral fermions, we find strong suppression of axial U(1) anomaly above the critical temperature of chiral phase transition. Our simulation data also indicate suppression of topological susceptibility compared to that predicted by the dilute instanton gas approximation (DIGA). In this talk, we present both of our theoretical and numerical evidence

We recently obtained an estimate of the axion mass based on the hypothesis
that axions make up most of the dark matter in the universe. A key ingredient
for this calculation was the temperature-dependence of the topological
susceptibility of full QCD. In the talk I summarize the calculation of the
susceptibility in a range of temperatures from well below the finite
temperature cross-over to a

Lattice computations are the only first principle method capable of quantitatively assessing the topological properties of QCD at high temperature, however the numerical determination of the topological properties of QCD, especially in the high temperature phase, is a notoriously difficult problem. We will discuss the difficulties encountered in such a computation and some strategies that have bee
