The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider, built by the European Organization for Nuclear Research (CERN) from 1998 to 2008. Its aim is to allow physicists to test the predictions of different theories of particle physics and high-energy physics, and particularly prove or disprove the existence of the theorized Higgs particle and of the large family of new particles predicted by supersymmetric theories. The LHC is expected to address some of the unsolved questions of physics, advancing human understanding of physical laws. It contains seven detectors, each designed for certain kinds of research.
The LHC was built in collaboration with over 10,000 scientists and engineers from over 100 countries,
as well as hundreds of universities and laboratories.
The Higgs Boson was discovered on July 4, 2012. The discovery has been called "monumental" because it appears to confirm the existence of the Higgs field, which is pivotal to the Standard Model and other theories within particle physics. Read more ...

The Higgs boson just revealed a new secret at the Large Hadron Collider Science Daily - August 25, 2025
ATLAS researchers have found evidence of the Higgs boson transforming into muons and refined their search for other rare decays, pushing the limits of what we know about this mysterious particle. The ATLAS Collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon. Since the discovery of the Higgs boson in 2012, physicists have made major strides in exploring its properties. Does that mean the subject is done and dusted? Far from it! In new results presented at the 2025 European Physical Society Conference on High Energy Physics (EPS-HEP), the ATLAS Collaboration narrowed in on two exceptionally rare Higgs-boson decays using data collected in Run 3 of the Large Hadron Collider (LHC). These studies offer deep insights into how closely the Higgs boson's behavior aligns with the Standard Model.

Cern: Scientists search for mysterious ghost particles BBC - March 25, 2024
Some physicists have long suspected that mysterious 'ghost' particles in the world around us could greatly advance our understanding of the true nature of the Universe. Now scientists think they've found a way to prove whether or not they exist. Europe's centre for particle research, Cern, has approved an experiment designed to find evidence for themThe new instrument will be a thousand times more sensitive to such particles than previous devices. It will smash particles into a hard surface to detect them instead of against each other like Cern's main device the Large Hadron Collider (LHC).
World's smallest particle accelerator is 54 million times smaller than the Large Hadron Collider, and it works Live Science - October 26, 2023
Scientists recently fired up the world's smallest particle accelerator for the first time. The tiny technological triumph, which is around the size of a small coin, could open the door to a wide range of applications, including using the teensy particle accelerators inside human patients. The new machine, known as a nanophotonic electron accelerator (NEA), consists of a small microchip that houses an even smaller vacuum tube made up of thousands of individual "pillars." Researchers can accelerate electrons by firing mini laser beams at these pillars.
Rare 'Hypernuclei' Have Been Detected at The Large Hadron Collider Science Alert - August 30, 2023
A rare type of particle has emerged from proton collisions in the Large Hadron Collider. Between 2016 and 2018, physicists recorded more than 100 rare, unstable hypernuclei - atomic cores that contain an unusual flavor of quark in one of their nuclear particles. It's a discovery that could help us understand the source of mysterious antihelium tentatively detected out in the great wide beyond of the cosmos. The Large Hadron Collider is what it sounds like: a giant machine for smashing particles together in high-speed collisions, so that physicists can pore over the remains and look for things like unstable, short-lived particles that we can't detect any other way.

CERN's Large Hadron Collider fires up for third time to unlock more secrets of the universe CNN - July 5, 2022

Now, physicists at the European Organization for Nuclear Research (CERN) on the Swiss-French border are restarting the collider with the aim of understanding more about the Higgs boson, other subatomic particles and the mysteries of dark matter - an invisible and elusive substance that can't be seen because it doesn't absorb, reflect or emit any light.

The Large Hadron Collider's official tally: 59 new hadrons and counting PhysOrg - March 3, 2021
How many new particles has the LHC discovered? The most widely known discovery is of course that of the Higgs boson. Less well known is the fact that, over the past 10 years, the LHC experiments have also found more than 50 new particles called hadrons. Coincidentally, the number 50 appears in the context of hadrons twice, as 2021 marks the 50th anniversary of hadron colliders: on 27 January 1971, two beams of protons collided for the first time in CERN's Intersecting Storage Rings accelerator, making it the first accelerator in history to produce collisions between two counter-rotating beams of hadrons.
LHC creates matter from light PhysOrg - September 4, 2020
The Large Hadron Collider plays with Albert Einstein's famous equation, E = mc2, to transform matter into energy and then back into different forms of matter. But on rare occasions, it can skip the first step and collide pure energy - in the form of electromagnetic waves. Last year, the ATLAS experiment at the LHC observed two photons, particles of light, ricocheting off one another and producing two new photons. This year, they've taken that research a step further and discovered photons merging and transforming into something even more interesting: W bosons, particles that carry the weak force, which governs nuclear decay. This research doesn't just illustrate the central concept governing processes inside the LHC: that energy and matter are two sides of the same coin. It also confirms that at high enough energies, forces that seem separate in our everyday lives - electromagnetism and the weak force - are united.
Long-sought decay of Higgs boson observed PhysOrg - August 28, 2018
Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. The finding, presented today at CERN1 by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), is consistent with the hypothesis that the all-pervading quantum field behind the Higgs boson also gives mass to the bottom quark. Both teams have submitted their results for publication today.
First-Ever Evidence of Higgs Boson Decay Opens New Doors for Particle Physics Live Science - August 28, 2018
If you've been a science fan for the last few years, you're aware of the exciting results to emerge from the Large Hadron Collider (LHC), which in 2012 found the Higgs boson, the subatomic particle responsible for giving mass to fundamental subatomic particles. Today, physicists have another exciting announcement to add to the Higgs saga: They have made the first unambiguous observation of Higgs bosons decaying into a matter-antimatter pair of bottom quarks. Surprisingly, the Higgs bosons decay most often in this way. The new announcement shows a strong agreement between the theoretical predictions and the experimental data, which could in turn set strict constraints on ideas of more fundamental physics that strive to explain why the Higgs boson even exists.
