Titre | Back to the future with the epsilon expansion |
Résumé | The epsilon expansion is a well-known framework in quantum field theory to construct weakly-coupled fixed points of the RG flow. Nevertheless, little is known about the landscape of theories it describes, beyond some well-known CFTs like the Ising and the O(N) models. In this talk we revisit the problem of classifying multiscalar fixed points, in the process proving new results their spectra. Moreover, we show that there is no weakly-coupled gauged fixed point with fewer than 183 flavors. |
