Gravitational Leptogenesis in Bounce Cosmology
Neil D. Barrie
We investigate whether successful Gravitational Leptogenesis can take place during an Ekpyrotic contraction phase. Two possible paths by which this can occur are coupling the Ekpyr…
Searching for Monopoles via Monopolium Multiphoton Decays
Neil D. Barrie, Akio Sugamoto, Matthew Talia +1
We explore the phenomenology of a model of monopolium based on an electromagnetic dual formulation of Zwanziger and lattice gauge theory. The monopole is assumed to have a finite-s…
Higgs Inflation, Vacuum Stability, and Leptogenesis
Neil D. Barrie, Akio Sugamoto, Tatsu Takeuchi +1
We consider the introduction of a complex scalar field carrying a global lepton number charge to the Standard Model and the Higgs inflation framework. The conditions are investigat…
Big Bounce Baryogenesis
Neil D. Barrie
We explore the possibility of an Ekpyrotic contraction phase harbouring a mechanism for Baryogenesis. A Chern-Simons coupling between the fast-rolling Ekpyrotic scalar and the Stan…
Broken Democracy with Intermediate Residual Symmetry and Random Perturbations
Neil D. Barrie, Shao-Feng Ge, Tsutomu T. Yanagida
The democratic mass matrix is an intriguing possibility for explaining the observed fermion mixings due to its inherent hierarchical mass eigenvalues and large mixing angles. Never…
Pendulum Leptogenesis
Kazuharu Bamba, Neil D. Barrie, Akio Sugamoto +2
We propose a new non-thermal Leptogenesis mechanism that takes place during the reheating epoch, and utilizes the Ratchet mechanism. The interplay between the oscillation of the in…
