The Higgs boson was discovered in 2012 by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), confirming a 50 year search for this elusive particle. It is responsible for giving mass to other fundamental particles, and its discovery was a major breakthrough in our understanding of the universe. The Higgs is a quantum of the Higgs field that permeates spacetime, and therefore the entire universe. When other particles interact with the Higgs field, they acquire mass. Through its vacuum expectation value, the Higgs field gives mass to elementary particles like quarks and electrons that interact with it.
The Higgs mechanism works as follows: Particles acquire mass by interacting with the Higgs field. The more a particle interacts with the field, the more mass it has. Quarks and electrons strongly couple to the Higgs, gaining significant mass. Neutrinos interact more weakly, resulting in tiny but non-zero mass. The photon does not interact with the Higgs at all, remaining massless. This Higgs mechanism elegantly explains the origins of mass for fundamental particles.
The discovery of the Higgs boson has opened up new possibilities for physics. It is possible that the Higgs boson could be used to develop new theories of physics that unify the four forces. This would be a major breakthrough in physics and would help us to understand the universe in a new way. It would mean that we would have a single theory that could explain all the forces of nature. This would be a significant step towards understanding the universe and our place in it.
One of the most exciting things about the Higgs boson is its potential to unify the four fundamental forces of nature: electromagnetism, the weak force, the strong force, and gravity. In the Standard Model of particle physics, these four forces are described as separate entities, but there is a growing body of evidence that they may be more closely related than we thought.
The strong nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom. The weak nuclear force is responsible for some types of radioactive decay. Electromagnetism is the force that governs electricity, magnetism, and light. And gravity is the force that attracts objects to each other.
The Higgs boson possibly unites the four forces in three ways. First, it is thought to be responsible for giving mass to all the other particles. This means that the Higgs boson is indirectly responsible for the strong, weak, and electromagnetic forces.
Second, the Higgs boson is thought to be the carrier of the Higgs field. The Higgs field is thought to be a unified field that underlies all four forces. This means that the Higgs boson is the "glue" that holds the four forces together.
In this article, I will discuss a third method of the Higgs boson uniting the four forces. I will focus on three specific sub-scenarios:
The Higgs boson uniting the electromagnetic force and the weak force.
The Higgs boson uniting the strong force, the electromagnetic force, and the weak force.
The Higgs boson uniting gravity with the other three forces.
The Higgs boson uniting the electromagnetic force and the weak force
The electromagnetic force and the weak force are two of the four fundamental forces of nature. The electromagnetic force is responsible for the forces between charged particles, such as electrons and protons. The weak force is responsible for radioactive decay and other processes that involve the transformation of particles.
The Higgs boson could unite the electromagnetic force and the weak force by the discovery in 2023 of the Higgs boson decaying into both photons and Z bosons. This suggests that the Higgs boson does indeed play a role in unifying the electromagnetic force and the weak force. The photon is the force-carrying particle of the electromagnetic force, and the Z boson is the force-carrying particle of the weak force. Via the Higgs boson containing both a photon and a Z boson, it would mean that the two forces are intimately related.
The Higgs boson uniting the strong force, the electromagnetic force, and the weak force
The strong force, the electromagnetic force, and the weak force are all known as "gauge forces." This means that they are mediated by force-carrying particles called gauge bosons. The strong force is mediated by gluons, the electromagnetic force is mediated by photons, and the weak force is mediated by the W and Z bosons.
The Higgs boson could unite the strong force, the electromagnetic force, and the weak force by virtue of the fact that they are created by gluon-gluon fusion. Gluons are the force-carrying particles of the strong force, and they are also scalar bosons. This scenario is supported by the fact that the Higgs boson has been observed to be produced in collisions of gluons. This suggests that the Higgs boson does indeed play a role in unifying the strong force, the electromagnetic force, and the weak force.
The Higgs boson uniting gravity with the other three forces
Gravity is the fourth fundamental force of nature. It is the force that binds us to the Earth and causes objects to fall to the ground. Gravity is also responsible for the formation of stars and galaxies. One challenge to unifying the four forces is that we do not yet know how to reconcile gravity with the other three forces. Reconciling gravity with the other three forces is hindered by the range of the mathematical effects of gravity not fitting with the range of the effects of the other three forces. Therefore, mathematically gravity is not renormalizable with the other three forces.
The Higgs boson could unite gravity with the other three forces by composite Higgs bosons creating Kaluza-Klein gravitons. Kaluza-Klein gravitons are hypothetical particles that would mediate the force of gravity in a higher-dimensional universe. If the Higgs boson could be shown to create Kaluza-Klein gravitons, it would provide strong evidence that the four forces are indeed unified.
This scenario is still speculative, but it is an exciting possibility. If the Higgs boson does indeed unify gravity with the other three forces, it would mean that we have finally found a way to describe the entire universe in a single unified theory.
Higgs Boson — Grand Unified Theory Equation
Here is one grand unified theory equation derived from the Higgs boson and its known and hypothetical properties, existing as a fundamental quantum field uniting the four forces:
gg → |H|² → γ + Z + KKg
The first part of the equation, gg → |H|², represents the creation of the composite Higgs boson from gluons, or the strong force. The second part of the equation, |H|² → γ + Z, represents the decay of the composite Higgs boson into a photon and a Z boson. The third part of the equation, |H|² → KKg, represents the decay of composite Higgs bosons into Kaluza-Klein gravitons.
This equation is a representation of the theory, and it is not yet experimentally verified. However, it provides a starting point for further research into this topic.
Conclusion
The Higgs boson is a fascinating particle that has the potential to revolutionize our understanding of the universe. Its discovery in 2012 was a major breakthrough, and it has opened up a new window into the fundamental nature of reality.
The scenarios discussed in this blog post are just a few of the ways in which the Higgs boson could unite the four forces. It is possible that there are other ways in which this could happen, and it is also possible that the Higgs boson will not be able to unify the four forces at all. However, the discovery of the Higgs boson and the electroweak force, has given us hope that we may one day be able to find a unified theory of the four forces of the standard model of physics.
