  • Axion-like fields heavier than about 10−27eV are expected to oscillate in the radiation dominated (RD) epoch when the Hubble parameter drops below their mass. Considering the Chern-Simons coupling with a dark gauge boson, large amount of dark photons are produced during a short time interval through tachyonic resonance instability. The produced dark photons then source gravitational tensor modes leading to chiral gravitational waves. Through this process, one can indirectly probe a large… CONTINUE READING
