Title: Calculation of the axion mass based on high-temperature lattice
quantum chromodynamics

Abstract: We present a full result for the equation of state (EoS) in 2+1+1
(up/down, strange and charm quarks are present) flavour lattice QCD. We
extend this analysis and give the equation of state in 2+1+1+1 flavour QCD.
In order to describe the evolution of the universe from temperatures
several hundreds of GeV to several tens of MeV we also include the known
effects of the electroweak theory and give the effective degree of
freedoms. As another application of lattice QCD we calculate the
topological susceptibility (chi) up to the few GeV temperature region.
These two results, EoS and chi, can be used to predict the dark matter
axion's mass in the post-inflation scenario and/or give the relationship
between the axion's mass and the universal axionic angle, which acts as a
initial condition of our universe.
