Cohen-Kaplan-Nelson Bound and Minimum Coupling in Effective Field Theories

Based on various dynamical arguments, we motivate a relation among the coupling strength, ultraviolet (UV), and infrared (IR) cutoff scales of an effective field theory. This relation, in conjunction with the Cohen-Kaplan-Nelson (CKN) bound connecting the UV and IR cutoff scales, implies a "Minimum Coupling Condition (MCC)." The derived MCC... Show more
