DESCRIPTION:\n    The existence of a primordial spectrum of gravitational 
 waves is a generic prediction of inflation\, and several CMB experiments a
 re going after their signatures. Here I will discuss how the coupling of a
  pseudoscalar inflaton to a gauge field can induce\, in a two-step process
 \, gravitational waves with unusual properties such as: (i) a net chiralit
 y (ii) a blue spectrum (iii) being detectable in the (relatively) near fut
 ure by ground-based gravitational interferometers (iv) large nongaussianit
 ies even if the scalar perturbations are approximately gaussian.\n\nhttps:
