The physics laboratory that houses the world’s largest atom accelerator announced on Tuesday the observation of three new “exotic particles” that could provide clues about the force that binds subatomic particles.
The observation of a new type of pentaquark and the first pair of tetraquarks at the European Organization for Nuclear Research (CERN, for its French acronym), which houses the Large Hadron Collider, offers a new angle to assess the “nuclear force”. strong” that holds the nuclei of atoms together.
Most exotic hadrons, which are subatomic particles, are made up of two or three elementary particles known as quarks.
The strong nuclear force is one of the four known forces in the universe, along with the weak nuclear force, the electromagnetic force, and gravity.
The announcement comes amid a flurry of activity this week at CERN: Also Tuesday, the HCG’s underground ring of superconducting magnets, propelling infinitesimal particles along a 27-kilometre (17-mile) circuit at a speed close to that of light, he began to make them collide again.
Collision data is captured by high-tech detectors along the circular path.
The stage known as “Season 3” of collisions, which ends a three-year hiatus for maintenance and other checks, runs at an unprecedented energy of 13.6 trillion electron volts, which will offer the possibility of new discoveries in particle physics.
CERN scientists are celebrating a good start to what is expected to be nearly four years of operation in “Season 3”, the third time the GHC has conducted collisions since its debut in 2008.
A day earlier, CERN celebrated the 10th anniversary of the confirmation of the Higgs boson, the subatomic particle that is at the center of the Standard Model that explains the foundations of particle physics.
