What is the Higgs Boson?
- The Higgs boson (or Higgs particle) is an elementary particle in the Standard Model of physics.
- Higgs Boson is associated with the Higgs field, making it the subatomic particle responsible for giving mass to other fundamental particles.
- It is difficult to detect the Higgs boson because: -
- The Higgs boson is very massive compared to other particles, so it does not last very long.
- There are usually no Higgs bosons around because it takes so much energy to make one.
What are Bosons?
- Bosons are one of the two fundamental classes of particles, the other being fermions.
- Bosons are responsible for the four fundamental forces of nature.
- Other known bosons are the photon, the W and Z bosons, and the gluon.
Large Hadron Collider:
- The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider and the largest single machine in the world.
- It was built by the European Organization for Nuclear Research (CERN) in collaboration with over 10,000 scientists and hundreds of universities, laboratories and countries.
- The aim of the LHC is to allow physicists to test the predictions of different theories of particle physics.
- A subatomic particle with the expected properties of Higgs Boson was discovered in 2012 by experiments at the Large Hadron Collider (LHC).
What is Standard Model?
- Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, and not including the gravitational force) in the universe, as well as classifying all known elementary particles.
- Gravity is most accurately described by the general theory of relativity.
