Correlation length of the angular mode for an approximate U(1) symmetry during inflation
It is known that a light scalar field obtains fluctuations in the de Sitter inflationary background. Such fluctuations could provide an initial condition for baryogenesis through the Affleck-Dine mechanism, where an approximate U(1)B symmetry is usually assumed. However, an interpretation of the bar...
