Higgs boson
From Achintya Rao’s Wiki
The Higgs boson was discovered by the ATLAS and CMS collaborations at CERN. The discovery was announced on 4 July 2012.

- All elementary particles were indeed massless just after the Big Bang.
- (Simplifying things here) The reason the electromagnetic and gravitational forces can be felt at the macro level is because they are mediated by massless particles (well, the “graviton” is only hypothetical at the moment). The strong force is also mediated by massless particles but “confinement” keeps the effects localised to a nucleon.
- With the discovery of a scalar in 2012, we knew that the field responsible for electroweak-symmetry breaking existed, but we could not yet say anything about how fermions got mass.
- The fact that the Higgs field is scalar is tied to the omnipotence of the field (unlike electromagnetism or gravity, that die out after some distance).
- The fact that the Higgs boson is a scalar is important.
- For follow-up at interview for feature: “We still don’t know if the particle we observed is the Standard Model Higgs boson.”
