  • Accelerators - CERN
    The Large Hadron Collider is the most powerful accelerator in the world It boosts particles, such as protons, which form all the matter we know Accelerated to a speed close to that of light, they collide with other protons These collisions produce massive particles, such as the Higgs boson or the top quark
  • From partons to hadrons - CERN
    They were able to follow the parton-to-hadron evolution from the parton shower stage, when the quarks and gluons are deconfined, to the hadronic phase, when the partons are confined within the hadrons Knowing the evolution of this process also helps to determine aS, the quantity that defines the strength of the strong force
  • The Large Hadron Collider | CERN
    The Large Hadron Collider The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator It 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
  • 59 new hadrons and counting - CERN
    The first hadron discovered at the LHC, χb (3P), was discovered by ATLAS, and the most recent ones include a new excited beauty strange baryon observed by CMS and four tetraquarks detected by LHCb The full list of new hadrons found at the LHC, organised by year of discovery (horizontal axis) and particle mass (vertical axis)
  • LHCb Collaboration discovers new proton-like particle | CERN
    The LHCb experiment at CERN’s Large Hadron Collider (LHC) has discovered a new particle consisting of two charm quarks and one down quark, a similar structure to the familiar proton, but with two heavy charm quarks replacing the two up quarks of the proton, thus quadrupling its mass The discovery, presented at the ongoing Moriond conference, will help physicists better understand how the
  • A bestiary of exotic hadrons - CERN
    The Large Hadron Collider (LHC) has discovered 76 new particles so far In addition to discovering the unique Higgs boson, the world’s largest and most powerful particle accelerator has found 52 new hadrons made up of two or three elementary particles called quarks and a bestiary of 23 oddities which confound easy explanation These exotic hadrons appear to be composed of four or five quarks
  • Home | CERN
    CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research Its business is fundamental physics, finding out what the Universe is made of and how it works
  • Facts and figures about the LHC - CERN
    Facts and figures about the LHC Why is it called the “Large Hadron Collider”? "Large" refers to its size, approximately 27km in circumference "Hadron" because it accelerates protons or ions, which belong to the group of particles called hadrons
  • ALICE detects the conversion of lead into gold at the LHC - CERN
    In a paper published in Physical Review Journals, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN’s Large Hadron Collider (LHC) Transforming the base metal lead into the precious metal gold was a dream of medieval alchemists This long-standing quest, known as chrysopoeia, may have been motivated by the observation that dull grey
  • And they’re off! The 2025 LHC physics season gets underway
    Today at 13h51, the engineer in charge of the LHC at the CERN Control Centre announced that stable beams had returned to the Large Hadron Collider (LHC), marking the start of the 2025 physics data-taking campaign, the fourth year of the LHC's third operating period (Run 3*) The 2025 campaign will
