  • 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
  • 59 new hadrons and counting - CERN
    The hadron discoveries from the LHC experiments keep coming, mainly from LHCb, which is particularly suited to studying particles containing heavy quarks 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
  • hadron - CERN
    A hadron is a subatomic particle that contains quarks, antiquarks, and gluons, and so experiences the strong force
  • The Large Hadron Collider - CERN
    The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator that pushes protons or ions to near the speed of light It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex The LHC consists of a 27-kilometre ring of superconducting magnets with a number of
  • ALICE detects the conversion of lead into gold at the LHC
    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
  • From partons to hadrons - CERN
    Physics experiments like those at CERN have shown that the world is made up of elementary particles Some of them, quarks, are forever bound within particles called hadrons Although scientists know that these elementary building blocks exist, they cannot describe exactly how quarks form protons or neutrons This lack of knowledge is due to a unique feature of the strong force, which is known
  • And they’re off! The 2025 LHC physics season gets underway
    (Image: CERN) 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 start with proton collisions at 13 6 TeV, and the proposed integrated luminosity
  • Old The Large Hadron Collider - CERN
    The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the
  • A ten-year journey through the quark–gluon plasma and beyond
    Hadron formation at high temperatures During the evolution of a heavy-ion collision, the QGP cools below the transition temperature and hadronises After this hadronisation, the energy density may be large enough to allow for inelastic (hadron-creating) interactions, which change the medium’s “chemical” composition, in terms of particle
  • Large Hadron Collider reaches its first stable beams in 2024
    On Friday 5 April, at 6 25 p m , the LHC Engineer-in-Charge at the CERN Control Centre (CCC) announced that stable beams were back in the Large Hadron Collider, marking the official start of the 2024 physics data-taking season The third year of LHC Run 3 promises six months of 13 6 TeV proton collisions at an even higher luminosity than before, meaning more collisions for the experiments to
