Inflation with vector fields revisited: non-Gaussianities
Chong-Bin Chen
We revisit the resulting bispectrum of inflation with kinetic-coupled vector fields by organizing the dynamics in terms of , which measures the vector kinetic contribution relat…

On the importance of heavy fields in pseudo-scalar inflation
Chong-Bin Chen, Ziwei Wang, Siyi Zhou
Pseudo-scalar inflation coupled with U(1) gauge fields through the Chern-Simons term has been extensively studied. However, new physics arising from UV theories may still influence…
