Seminar:- Primordial Gravitational Waves from an Inflaton-Gauge Interaction
In this talk, the speaker will focus on a gauge field interacting with the inflaton through an exponential type coupling function. It is known that such a coupling is ubiquitous from higher dimensional fundamental theory. He will show that the gauge field grows at the later stage of inflaton due to the interaction. Consequently, high-frequency gravitational waves are induced by such gauge field production.
