Subject : GENERAL SCIENCE (PHYSICS)
Standard Model
- The standard model is a theory of Particle Physics.
- It says all the material around us is made up of 12 matter particle (also known as Fermions).
- The other 11 particles predicted by the model have been found and only Higgs particle was not yet found, so the CERN was trying to find it.
CERN
- The European Organization for Nuclear Research also known as CERN
- It is the world’s largest nuclear physics laboratory carrying out various experiments,
- It is situated at Geneva, along France-Swiss border.
- It has been operating several particle accelerators the latest one being the Large Hadron collider.
Higgs boson Particle
- This particle is theoretically responsible for mass, without which there would be no gravity and no universe.
- Therefore it is also called the “God” particle.
- The Higgs particle was proposed in the 1960s by British physicist Peter Higgs as a way of explaining why other particles have mass.
- CERN has been attempting to find evidence of its existence.
Large Hadron Collider
- The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator.
- The LHC consists of a 27 kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
- Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide.
- The beams travel in opposite directions in separate beam pipes – two tubes kept at ultra high vacuum.
Bose in ‘Boson’
- The work done by Bose and Albert Einstein laid the foundation for the discovery of the God particle.
- The sub-atomic particle “boson” is named after Bengali physicist Satyendra Nath Bose whose pioneering work in the field in the early 1920s changed the way particle physics has been studied.
- He was awarded India’s second highest civilian award, the Padma Vibhushan in by the Government of India.
- What makes totally awesome- he never received a Ph.D, nor was he awarded a Nobel Prize, though the Nobel committee recognised other scientists for research related to concepts he developed.
Who is Archana Sharma ?
A scientist of Indian origin, working at CERN involved in CMS experiment over there. She has been involved in this since 1987.
