Large Hadron Collider has successfully started
Ten years after the discovery of the Higgs boson, the Large Hadron Collider is activating for the third time with a record energy of 13.6 trillion electron volts.
Data from the third operation of the LHC may provide evidence for physics beyond the standard model of particle physics, such as dark matter and dark energy.
The Standard Model explains how the basic building blocks of matter, governed by the four fundamental forces, interact.
Increased collision rates, higher collision energy, upgraded data readout and selection systems, new detector systems and computing infrastructure: all these factors point to a promising physics season that will further expand the already very diverse LHC physics programme.
Dark Matter:
Dark matter is matter that does not absorb, reflect or emit light. Because of this it becomes extremely difficult to identify it. Dark energy is the mysterious influence that drives the rapid expansion of the universe.
Large Hadron Collider (LHC)
- The LHC is the most powerful machine ever to accelerate a particle. It accelerates protons or ions almost equal to the speed of light. It is located at the European Particle Physics Laboratory at CERN.
- It has a ring of superconducting magnets (in a tunnel 100 meters below the ground) of 27 km. It consists of several structures providing acceleration, which increases the energy of the particles in the path.
- It is used on a particle detector to measure the energies, directions and velocities of these particles for colliding accelerated protons or lead ions. These four detectors are ATLAS, CMS, ALICE and LHCb.
Higgs Boson:
- It was first predicted by Peter Higgs in the 1960s.
- This will help to understand why elementary particles have mass. Elemental particles are the smallest building blocks of nature.
- The Higgs boson has confirmed the predictions of the Standard Model of particle physics.
- Every known particle except the Higgs boson has a quantum spin.
