What is The Large Hadron Collider
The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator. It is located at the European Organization for Nuclear Research (CERN) near Geneva, Switzerland. The LHC is designed to study the fundamental particles and forces that make up the universe.
Here are some key facts about the LHC:
1. Size and Structure:The LHC is a circular tunnel with a circumference of 27 kilometers (17 miles). It is located about 100 meters (330 feet) underground and crosses the borders between Switzerland and France.
2. Particle Acceleration:
The LHC uses powerful magnets to accelerate two beams of particles, typically protons, in opposite directions around the ring. The particles are accelerated to nearly the speed of light before being made to collide at four different detector locations along the ring.
3. Collisions and Detectors:
When the beams of particles collide, the energy released allows scientists to study the fundamental properties of matter and the universe. The LHC has four main detectors: ATLAS, CMS, ALICE, and LHCb. These detectors are massive and collect data from collisions to help scientists understand the particles and processes involved.
4. Discovery of the Higgs Boson:
One of the primary goals of the LHC was the discovery of the Higgs boson, a particle that explains the origin of mass in the universe. In 2012, the ATLAS and CMS experiments announced the discovery of a new particle consistent with the Higgs boson, leading to the award of the Nobel Prize in Physics in 2013.
5. Energy and Intensity:
The LHC has undergone several upgrades since its first operation in 2008. The most significant upgrade, known as the "High-Luminosity LHC," is currently being planned to increase the luminosity and intensity of the particle beams, allowing for more precise measurements and the potential discovery of new particles or phenomena.
6. Scientific Research:
The LHC enables scientists to conduct experiments in high-energy physics. It has been instrumental in studying the properties of known particles, searching for new particles (such as supersymmetric particles or dark matter candidates), and exploring the conditions present shortly after the Big Bang.

This discovery confirmed the existence of the Higgs field and provided crucial insights into the origin of mass in the universe.
Supersymmetry is a theoretical extension of the Standard Model that suggests the existence of new particles that could help solve some unanswered questions in physics. The LHC has been actively searching for evidence of supersymmetric particles since its operation. So far, no conclusive evidence has been found, but the searches continue.
3. Measurements of Standard Model Particles:
The LHC has also been instrumental in the precision measurements of particles within the framework of the Standard Model of particle physics. It has provided valuable data on the properties and behaviors of known particles, including the top quark, the W and Z bosons, and the charm and strange quarks.

This research provides insights into the behavior of quarks and gluons in extreme conditions and helps us understand the evolution of the universe.
5. Search for Dark Matter Candidates:
Dark matter, which constitutes a significant portion of the universe's mass, has not yet been directly observed. The LHC has conducted experiments to search for particles that could potentially be dark matter candidates. These experiments aim to identify any signals or interactions that could be attributed to dark matter particles.
6. Tests of Fundamental Physics Theories:
The LHC has been used to test various theories beyond the Standard Model, such as extra dimensions, string theory, and quantum gravity. By colliding particles at high energies, scientists hope to find deviations from the predictions of the Standard Model that could indicate new physics or phenomena.
These experiments and discoveries made at the LHC have significantly advanced our understanding of particle physics, the fundamental nature of matter, and the early universe.
The LHC continues to operate and collect data, enabling scientists to delve further into the mysteries of the universe and search for new phenomena beyond our current knowledge.
