Dark Photon Decay Beyond The Euler-Heisenberg Limit
Samuel D. McDermott, Hiren H. Patel, Harikrishnan Ramani
We calculate the exact width for a dark photon decaying to three photons at one loop order for dark photon masses m' below the e+e- production threshold of 2m_e. We find substantia…
On the Decoupling Theorem for Vacuum Metastability
Hiren H. Patel, Branimir Radovcic
In this paper, we numerically study the impact heavy field degrees of freedom have on vacuum metastability in a toy model, with the aim of better understanding how the decoupling t…
Transplanckian Censorship and Global Cosmic Strings
Matthew J. Dolan, Patrick Draper, Jonathan Kozaczuk +1
Large field excursions are required in a number of axion models of inflation. These models also possess global cosmic strings, around which the axion follows a path mirroring the i…
