چکیده
|
We calculate 1-loop corrections to the schwinger-keldysh propagators of standard-model-like fields of spin-0, 1/2, and 1, with all renormalizable interactions during inflation. we pay special attention to the late-time divergences of loop corrections, and show that the divergences can be resummed into finite results in the late-time limit using dynamical renormalization group method. this is our first step toward studying both the standard model and new physics in the primordial universe.
