What exactly is a Yang-Mills Theory? Is it a general theory, based on SU(N) symmetry, which can then be applied for particular cases (ElectroWeak, Chromodynamics) ? Is it like a general mathematical model of gauge theory ?

Yang-Mills theory is a theoretical framework in physics that describes the interactions between elementary particles. It is based on a symmetry principle known as SU(N) symmetry, which involves a mathematical structure called a gauge theory.
SU(N) symmetry is a type of symmetry that describes the behavior of systems composed of N components. In Yang-Mills theory, this symmetry is used to describe the interactions between elementary particles, such as quarks and gluons.
Gauge theory is a mathematical framework that describes the behavior of particles and fields in a four-dimensional space-time. In Yang-Mills theory, gauge theory is used to describe the interactions between particles by introducing a gauge field that mediates the interactions.
Yang-Mills theory is significant because it provides a theoretical framework for understanding the fundamental interactions between particles, such as the strong and weak nuclear forces. It has also played a crucial role in the development of the Standard Model of particle physics.
Yang-Mills theory is the basis of quantum chromodynamics, which is the theory of the strong nuclear force. QCD is a specific application of Yang-Mills theory to the behavior of quarks and gluons, and it is one of the pillars of the Standard Model of particle physics.
