Ultraviolet completion

Ultraviolet (UV) completion refers to a theoretical framework within particle physics that addresses the behavior of a quantum field theory at very high energy scales. In many quantum field theories (QFTs) or models, the interactions and particles exhibit divergences or inconsistencies when energy scales approach very high values, typically on the order of the Planck scale (\(10^{19}\) GeV) or at energies significantly higher than those probed by current experiments.
