GENEVA 

The physics lab that houses the world's largest atomic collider announced Tuesday that it was observing three new "exotic particles" that could provide clues to the force that binds subatomic particles. Observing a new type of pentaquark and the first tetraquark duo at CERN, the Geneva area hosting the Large Hadron Collider, offers a new point of view for evaluating the "strong force" 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 force is one of the four forces known in the universe, along with the "weak force", which applies to the decomposition of particles, as well as to the electromagnetic force and gravity.

The announcement comes amid a flurry of activity this week at CERN:

Also on Tuesday, the LHC's subterranean ring of superconducting magnets pushing infinitesimal particles along a 27-kilometer (about 17-mile) circuit and almost at the speed of light. , he started joining them again. . Collision data is acquired by high-tech detectors along the circular path. The so-called "Run 3" of collisions, which ends a three-year hiatus for maintenance and other checks, is operating at an unprecedented energy of 13.6 trillion electron volts, offering the prospect of new breakthroughs in the physics of particles.

hailed the smooth start to what should be nearly four years of "Run 3" operation, the third time the LHC has made collisions since its debut in 2008.

The day before, CERN celebrated the 10th anniversary of the confirmation of the Higgs boson, the subatomic particle that occupies a central place in the so-called Standard Model that explains the fundamentals of particle physics.
