Axions in the early Universe

  • 1. Max-Planck-Institut fuer Physik, Muenchen (Germany)

Description

The smallness of the CP violating term in the QCD Lagrangian is the well known strong CP problem. If it is solved via the Peccei-Quinn (PQ) mechanism, the pseudo-Nambu-Goldstone boson associated with the spontaneous breaking of the new chiral U(1)PQ symmetry is the axion. We study the behavior of axions in the early Universe and calculate the temperature at which the axion decouples from the early QCD plasma.
