Abstract

Dilaton effective field theory (dEFT) describes the long distance behavior of certain confining, near-conformal gauge theories that have been studied via lattice computation. Pseudo-Nambu-Goldstone bosons (pNGBs), emerging from the breaking of approximate, continuous, internal symmetries, are couple...
