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
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
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
hadron - CERN A hadron is a subatomic particle that contains quarks, antiquarks, and gluons, and so experiences the strong force
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
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
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
Facts and figures about the LHC - CERN "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 "Collider" because the particles form two beams travelling in opposite directions, which are made to collide at four points around
