A bstract We study a predictive model for explaining the apparent deviation of muon anomalous magnetic moment from Standard Model expectation. There are no new scalars and hence hierarchy puzzles beyond those associated with Higgs; only particles at TeV scale vector-like singlet doublet leptons. Interestingly, this simple provides calculable example violating Wilsonian notion naturalness: despi...

We show that our Universe lives in a topological and non-perturbative vacuum state full of large amount hidden quantum hairs, the hairons. will discuss elaborate on theoretical evidences hairs are related to gravitational winding number vacuo. Thus, hairons originated from degrees freedom, holographically stored de Sitter area. The hierarchy Planck scale over Cosmological Constant (CC) is under...

Abstract Conceptual spaces are a frequently applied framework for representing concepts. One of its central aims is to find criteria what makes concept natural. A prominent demand that natural concepts cover convex regions in conceptual spaces. The first aim this paper analyse the convexity thesis and arguments have been advanced favour or against it. Based on this, I argue most supporting focu...
