The inflationary universe could be an interesting testbed of beyond the Standard Model theories at energies far above the reach of terrestrial colliders. In this talk, I will discuss the production of massive U(1) gauge bosons during inflation and show that it creates gravitational waves with characteristic signature detectable at PTA, LISA and LIGO interferometers. I will also talk about the prospect of detecting nongaussianity and parity violation in these signals.
