Definition of coupling constant in English:

coupling constant

noun

Physics

A constant representing the strength of the interaction between a particle and a field.
〔物理〕耦合常数
Example sentencesExamples
- That's an important detail, because the size of the gravitational coupling constant is what determines the distance scale of quantum gravity.
- But its predictions for the coupling constants - the constants that describe the strengths of the strong, weak and electromagnetic interactions - were wrong.
- As I mentioned, the coupling constant of string theory is not really a constant at all, and in many respects it is very similar to the compactification moduli.
- Newton's constant is the coupling constant for the gravitational force, for example.
- For electromagnetism, the coupling constant is called the fine structure constant a and is formed by the electron charge, Planck's constant and the speed of light.
