Predicting the mass of QCD axion based on a universal scaling relation for quantum fluids
Oral-Virtual
Abstract
I will present experimental data on various systems which undergo
a phase transition to a condensed state, such as superconductors and
superfluids. The data indicates that there is a universal correlation
between their condensation temperatures, effective mass of condensing
particles and coherence length of the condensate. Assuming that
QCD axion also follows the same correlation, I use it to estimate
the mass of the axion. The best estimate puts the mass in the
10-100 MeV range, which is consistent with some theoretical proposals.
