Abstract: A bstractThe QCD axion’s coupling to photons is often assumed to lie in a narrow band as a function of the axion mass. We demonstrate that several simple mechanisms, in addition to the photophilic clockwork… read more here.

Abstract: We consider the order parameter u = 〈Trφ2〉 as function of the running coupling constant τ ∈ H of asymptotically free N = 2 QCD with gauge group SU(2) and Nf ≤ 3 massive hypermultiplets.… read more here.
