Abstract

Dilaton effective field theory (dEFT) can be employed to analyze lattice data in gauge theories thatlie in close proximity of the lower edge of the conformal window. Under special conditions, we showthat it can be used as a diagnostic tool to distinguish near-conformal, yet confining, theories fromi...
