"Walking, Weak first-order transitions, and Complex CFTs II. Two-dimensional Potts model at Q>4" by Victor Gorbenko, Slava Rychkov, Bernardo Zan has received the Select label. Warm congratulations to the authors!
This theoretical high energy physics paper studies the slow Renormalization Group (RG) evolution using a 2D Potts model with Q > 4. First, the authors define new complex Conformal Field Theories (CFTs). Then, these new CFTs are used to develop a conformal perturbation approach that describe slow real coupling trajectories in the vicinity of these complex CFTs. The Potts model was used to develop these CFTs because, apart from its own significance, it serves as an ideal playground for testing this very general relation. Here, one will find a thorough discussion of all conceptual issues related to the topic, and the theories developed can be further used as a smoking gun for detecting walking in Monte Carlo simulations.
