CERN Collider discovered the existence of New Force of Nature

Context

The scientists working at CERN Collider have seen evidence of the existence of a new force of nature.

The Standard Model of fundamental particles

• The universe is found to be constituted of a few basic building blocks which are known as fundamental particles. These particles are governed by four fundamental forces.
• The interaction between the particles and three of the forces was studied through a model of particle physics developed in the 1970s.
• The standard model says that nature is studied at a fundamental scale through particles known as lepton and quarks and the forces which exist between them.
  • The beauty quarks (one of the subtypes of quark) decay into leptons known as ‘muons’.

New finding

• A difference in the decay rate of muons and electrons was observed.
• Reason: It is expected that a new unseen particle or force is behind this differential rate of decay.
  • Two particles Z prime and lepto-quark are considered to be the expected particles as a part of the experiment to support the finding.

Significance of the finding

• It could help in finding the new fundamental particles which will the physical phenomenon further.
  • It could help in studying the invisible dark matter or nature of Higgs boson.
