The Large Hadron Collider started working again after a gap. An LHC experiment, ‘The Large Hadron Collider beauty (LHCb) experiment’, has observed three never-before-seen particles.
Write a brief note on the Large Hadron Collider (LHC) and its LHCb Experiment.
Electron volt and Tera electron volts
An electron volt is the energy given to an electron by accelerating it through 1 volt of electric potential difference.
A TeV is 100 billion, or 10-to-the-power-of-12, electron volts.
Higgs boson/God Particle
The Higgs boson is the fundamental particle associated with the Higgs field.
The Higgs field is a field that gives mass to other fundamental particles such as electrons and quarks.
A particle’s mass determines how much it resists changing its speed or position when it encounters a force.
Not all fundamental particles have mass. The photon, which is the particle of light and carries the electromagnetic force, has no mass at all.
The Higgs boson was proposed in 1964 by Peter Higgs, François Englert, and four other theorists to explain why certain particles have mass.
Scientists confirmed its existence in 2012 through the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN in Switzerland.
This discovery led to the 2013 Nobel Prize in Physics being awarded to Higgs and Englert.
The term new physics refers to a range of fundamental developments and paradigm shifts that occurred in the physical sciences during the last half of the twentieth century.
These include The theory of quarks, which is essential to the standard model of fundamental particle physics
The study and application of macroscopic manifestations of quantum phenomena such as superconductivity, super-fluidity, lasing, and other types of spontaneous quantum self-organization;
The realization of electroweak unification and the quests for grand and total unification of the four fundamental interactions;
The burgeoning successes in gravitational physics, including gravitational wave and black hole physics; Inflationary, fundamental-particle, and quantum cosmology, which ultimately rely on total unification and quantum gravity schemes.
CERN began in the 1950s as the European Organization for Nuclear Research.
Today it is also known as the European Laboratory for Particle Physics.
It is one of the world's most prestigious research centers in the field of Particle Physics.
Its business is fundamental physics - finding out what makes our Universe work, where it came from and where it is going.
At CERN, some of the world's biggest and most complex machines are used to study nature's tiniest building blocks, the fundamental particles. By colliding these minute particles of matter physicists unravel the basic laws of nature.
CERN is the world’s largest nuclear and particle physics laboratory.
CERN is based in Geneva on the French-Swiss border. Presently CERN has 23 member states. India is an associate member of the CERN.
