Summary
Coupling Constants
are
Fundamental parameters in physics
that quantify the
Strength of interactions
between
Particles or fields
, playing a crucial role in determining the dynamics and
Outcomes of physical processes
. They are essential in the
Formulation of theories
such as
Quantum Electrodynamics
(QED),
Quantum Chromodynamics
(QCD), and the
Standard Model Of Particle Physics
, where they dictate the
Rates of particle decays
and
Scattering Processes
.
