what does it mean when they say the Gauge "Sector" of SM?
what other sectors are there?
Thanks

The Gauge Sector of the Standard Model refers to the part of the model that describes the fundamental forces of nature. These forces are mediated by particles known as gauge bosons, which are responsible for interactions between particles.
The fundamental forces in the Gauge Sector of the SM are the strong nuclear force, the weak nuclear force, the electromagnetic force, and the gravitational force. These forces are responsible for all interactions between particles and play a crucial role in the behavior of matter.
The Gauge Sector of the SM explains the behavior of particles through the exchange of gauge bosons. These particles carry the fundamental forces and allow particles to interact with each other. The behavior of particles is described by mathematical equations known as gauge theories.
When physicists say the Gauge Sector is "broken", they are referring to a phenomenon known as spontaneous symmetry breaking. This occurs when the symmetry of the gauge bosons is broken, leading to the acquisition of mass by some particles and the emergence of different interactions between particles.
The Gauge Sector of the SM is closely related to the Higgs boson, which is responsible for giving particles their mass through the process of electroweak symmetry breaking. The Higgs boson is a fundamental particle predicted by the SM and was discovered in 2012 by the Large Hadron Collider at CERN.
