How is the electroweak symmetry actually broken in the standard model ?
Please could you explain the idea to me.
Thanks
Roger.

roger said:What do you mean by ''degenerate (symmetric) vacuum '' exactly ?
WE SAY STATES ARE DEGENERATE IF THEY HAVE THE SAME QUANTUM NUMBERS.i.e. THEY BELONG TO THE SAME REPRESENTATION OF THE SYMMETRY GROUP IN QUESTION.JUST THINK OF THEM AS STAES HAVING THE SAME ENERGY.
THESE ARE GAUGE PARTICLES,LIKE THE PHOTON, WITH SPIN=1. THEREFORE THEY ARE MESONS. IN GAUGE FIELD THEORIES, THE GAUGE FIELD FUNCTIONS, WHICH REPRESENT THE GAUGE PARTICLES, CARRY A SPACETIME INDEX.i.e.THEY ARE SPACETIME VECTORS.And why do you refer to the w and z particles as vector mesosn ?
READ MY POST. YOU COULD SAY THE SAME THING WHICH CAUSES PHASE TRANSITION.what causes the spontaneous breakdown of symmetry ?
Roger, you didn't tell me why did you choose me to answer your question.

Electroweak symmetry breaking is a fundamental process in particle physics that explains how the weak nuclear force and electromagnetic force, which were once thought to be the same force, became distinct. It is responsible for giving particles mass and allows for the formation of the universe as we know it.
Electroweak symmetry breaking occurs when the Higgs field, a theoretical field that permeates the universe, is activated. This field interacts with particles, giving them mass and causing the weak nuclear force to become distinct from the electromagnetic force.
One of the most significant pieces of evidence for electroweak symmetry breaking is the discovery of the Higgs boson particle in 2012 at the Large Hadron Collider. This discovery confirmed the existence of the Higgs field and its role in electroweak symmetry breaking.
Electroweak symmetry breaking is crucial for understanding the fundamental forces that govern our universe. It also helps explain why certain particles have mass and others do not. Without this process, the universe would look very different, and life as we know it would not be possible.
Yes, electroweak symmetry breaking is still an active area of research in particle physics. Scientists are trying to understand the exact mechanism of this process and how it relates to other fundamental physics theories, such as supersymmetry. This research could lead to new discoveries and a deeper understanding of the laws of the universe.
