This implies that we might be able to start probing theories that go beyond the simplest single-field inflationary scenario, as an effective single-field theory coming from a two-field inflation framework. In particular, in this work, we study the (scale-dependent) bias in galaxy clustering that comes from an effective field theory, whose effect in the inflaton dynamics is a transient reduction in the speed of sound.Show less
