Non-Abelian Strings and Axions
We address two distinct but related issues: (i) the impact of (two-dimensional) axions in a two-dimensional theory known to model confinement, the CP (N−1) model; (ii) bulk axions in four-dimensional Yang–Mills theory supporting non-Abelian strings. In the first case n, n̄ kinks play the role of “quarks.” They are known to be confined. We show that introduction of axions leads to deconfinement (...
متن کاملAxions, Monopoles and Cosmic Strings
We are discussing some aspects of the magnetic monopoles and cosmic strings interactions with axion domain walss and membranes. The monopole moving through an axion domain wall is transformed into a monopole bag the state with a dyon quantum number, but smaller mass. In the case of an axion membrane the passing monopole excites the chiral charged state at the membrane boundary. It will be shown...
متن کاملTopological strings live on attractive manifolds
We add to the mounting evidence that the topological B model’s normalized holomorphic three-form has integral periods by demonstrating that otherwise the B2-brane partition function is ill-defined. The resulting Calabi-Yau manifolds are roughly fixed points of attractor flows. We propose here that any admissible background for topological strings requires a quantized (twisted) integrable pure s...
متن کاملAxions from wall decay
We discuss the decay of axion walls bounded by strings and present numerical simulations of the decay process. In these simulations, the decay happens immediately, in a time scale of order the light travel time, and the average energy of the radiated axions is 〈ωa〉 ≃ 7ma for va/ma ≃ 500. 〈ωa〉 is found to increase approximately linearly with ln(va/ma). Extrapolation of this behaviour yields 〈ωa〉...
متن کاملNew Directions for New Dimensions: from Strings to Neutrinos to Axions
In this talk, I discuss recent developments concerning the possibility of large extra spacetime dimensions. After briefly reviewing how such dimensions can lower the fundamental GUT, Planck, and string scales, I then outline how these scenarios lead to a new higher-dimensional seesaw mechanism for generating neutrino oscillations — perhaps even without neutrino masses. I also discuss how extra ...
