摘要
A mechanism for lifting the cosmological upper bound on the axion decay constant, , is proposed. It entails the near masslessness of the radial mode whose vacuum expectation value is . Energy in the coherent oscillations of the axion field in the early universe gets fed into the motion of the radial mode, from which it is then redshifted away.
