Baryogenesis from Unstable Domain Walls

. -ABSTRACT _ There exists a class of cosmic strings that turn matter into antimatter (Alice strings). In a GUT where the unbroken gauge group contains charge conjugation (C), such strings form when a phase transition renders C a discrete symmetry. They become boundaries of domain walls at a later, C-breaking transition. These ‘Alice walls’ are cosmologically harmless, but -. can play an import...

Reviews of evidence on interventions to prevent dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries.

This report presents the results of systematic reviews of effectiveness, applicability, other positive and negative effects, economic evaluations, and barriers to use of selected population-based interventions intended to prevent or control dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries. The related systematic reviews are linked by a common conceptual appro...

Breaking down barriers to initiating insulin: Insulin prescription pad.

Many patients with type 2 diabetes mellitus (T2DM) require insulin therapy to achieve and maintain glycemic control.1 Family physicians provide most of the care for these patients and are usually the first point of contact in the insulin conversation. Therefore, it is important that family physicians have the knowledge and skills to initiate and titrate insulin, and any additional tools they ca...

Real Time Thermal Propagators for Massive Gauge Bosons

We derive Feynman rules for gauge theories exhibiting spontaneous symmetry breaking using the real-time formalism of finite temperature field theory. We also derive the thermal propagators where only the physical degrees of freedom are given thermal boundary conditions. We analyse the abelian Higgs model and find that these new propagators simplify the calculation of the thermal contribution to...
