The cut-off scale is a threshold in a physical theory beyond which the current model ceases to be valid, often indicating the energy level where new physics or a more fundamental theory is required. It serves as a boundary for the applicability of effective field theories, helping to separate known physics from unknown phenomena that require further investigation or a different theoretical framework.

Cut-off Scale

Threshold in a physical theory

Current model

In physics, an energy level refers to the fixed energies that a quantum system such as an atom, electron, or nucleus can have. These discrete energy levels play a critical role in determining the chemical and physical properties of matter, influencing how atoms bind with each other and interact with electromagnetic radiation.

Energy Level

New Physics refers to theoretical developments and experimental discoveries that extend or challenge the current understanding of fundamental forces and particles, as described by the Standard Model. It seeks to address unresolved questions such as dark matter, dark energy, and the unification of gravity with quantum mechanics, potentially leading to groundbreaking shifts in our comprehension of the universe.
