Self-consistent solitons for vacuum decay in radiatively generated potentials
Bjorn Garbrecht, Peter Millington
We use a Green's function approach in order to develop a method for calculating the tunneling rate between radiatively-generated non-degenerate vacua. We apply this to a model that…
Constraining the effective action by a method of external sources
Bjorn Garbrecht, Peter Millington
We propose a novel method of evaluating the effective action, wherein the physical one- and two-point functions are obtained in the limit of non-vanishing external sources. We illu…
Non-Hermitian extension of gauge theories and implications for neutrino physics
Jean Alexandre, Carl M. Bender, Peter Millington
An extension of QED is considered in which the Dirac fermion has both Hermitian and anti-Hermitian mass terms, as well as both vector and axial-vector couplings to the gauge field.…
Corrigendum to "Flavour Covariant Transport Equations: an Application to Resonant Leptogenesis"
P. S. Bhupal Dev, Peter Millington, Apostolos Pilaftsis +1
We amend the incorrect discussion in Nucl. Phys. B 886 (2014) 569 [1] concerning the numerical examples considered there. In particular, we discuss the viability of minimal radiati…
Negative-frequency modes in quantum field theory
Robert Dickinson, Jeff Forshaw, Peter Millington
We consider a departure from standard quantum field theory, constructed so as to permit momentum eigenstates of both positive and negative energy. The resulting theory is intriguin…
Flavour effects in Resonant Leptogenesis from semi-classical and Kadanoff-Baym approaches
P. S. Bhupal Dev, Peter Millington, Apostolos Pilaftsis +1
Flavour effects play an important role in the statistical evolution of particle number densities in several particle physics phenomena. We present a fully flavour-covariant formali…
Green's function method for handling radiative effects on false vacuum decay
Bjorn Garbrecht, Peter Millington
We introduce a Green's function method for handling radiative effects on false vacuum decay. In addition to the usual thin-wall approximation, we achieve further simplification by…
