Description

"Inflation offers the highest energy scale that we can probe in physics. Massive spinning fields during inflation leave distinct imprints in the form of CMB correlators. We explore the most general massive spin-1 field during inflation by imposing microcausality, which has two (and no more) extra parameters that can be probed in the trispectrum (but not bispectrum)."
