  • Peter W. Higgs received Nobel Prize in Physics (2013) jointly with Francois Englert for theoretical discovery of mechanism influencing origin of subatomic particle mass.
  • He theorized the existence of Higgs Boson in 1964. It was finally discovered in 2012 at Large Hadron Collider (LHC).
    • LHC is world’s largest particle accelerator located European particle physics laboratory CERN, Switzerland.

 

  • Higgs Boson
    • Higgs boson is the fundamental particle associated with Higgs field, a field that gives mass to other fundamental particles.
      • Particle’s mass depends upon their interaction with this Higgs field.
      • Photons do not interact with this field and are thus massless.
      • Particles like electrons and protons do interact and have masses
    • Higgs boson itself interacts with this field and thus has mass.
    • Concept of Higgs field and Higgs particle are fundamental to our current understanding of way nature works.

 

  • Other fundamental Particles
    • Fermions (12 in number)-They are building blocks of matter and are split into six quarks and six leptons.
    • Bosons are particles that carry energy and forces throughout universe.
