Renormalisation and invariants for two U(1)s
Sacha Davidson, Martin Gorbahn
We revisit the renormalisation of models with two U(1) gauge symmetries, in a formulation with non-canonical gauge kinetic terms which is covariant under field reparametrisations a…
Old and new physics interpretations of the NuTeV anomaly
S. Davidson, S. Forte, P. Gambino +2
We discuss whether the NuTeV anomaly can be explained, compatibly with all other data, by QCD effects (maybe, if the strange sea is asymmetric, or there is a tiny violation of isos…
Protecting the Baryon Asymmetry with Thermal Masses
S. Davidson, K. Kainulainen, K. A. Olive
We consider the evolution of baryon number in the early universe under the influence of rapid sphaleron interactions and show that will remain nonzero at all times even in…
Astrophysical Bounds on Milli-Charged Particles in Models with a Paraphoton
Sacha Davidson, Michael Peskin
The upper bound on the number of relativistic species present at nucleosynthesis has been used to constrain particles with electric charge (). We correct the bo…
Inflation, Neutrino Baryogenesis, and (S)Neutrino-Induced Baryogenesis
B. A. Campbell, S. Davidson, K. A. Olive
We evaluate the constraints that the COBE observations put on baryogenesis in inflationary cosmologies.We consider the supersymmetric version of the proposal of Fukugita and Yanagi…
Supersymmetric (S)Neutrino-Mass Induced Baryogenesis
B. A. Campbell, S. Davidson, K. A. Olive
We propose a new mechanism for baryogenesis in supersymmetric extensions of the standard model, that does not depend on (super)GUT interactions. It occurs by the non-perturbative e…
On the Baryon, Lepton-Flavour and Right-Handed Electron Asymmetries of the Universe
B. A. Campbell, S. Davidson, J. Ellis +1
Non-perturbative electroweak effects, in thermal equilibrium in the early universe, have the potential to erase the baryon asymmetry of the universe, unless it is encoded in a B-L…
