All-Loop Renormalization and the Phase of the de Sitter Wavefunction
Alexander Farren, Ciaran McCulloch, Enrico Pajer +1
Cosmological observables of the primordial universe are encoded in the late-time field-theoretic wavefunction. For shift-symmetric scalars in de Sitter, a good approximation for ma…

Spurious Isospin Breaking in the In-medium Similarity Renormalization Group
A. Farren, S. R. Stroberg
Robustly quantifying the uncertainty in the isospin-related theoretical correction to superallowed beta decay rates is vital for a correct assessment of CKM unitarity. To th…
