The Large Hadron Collider Discovers Three Particles Previously Unobserved.
Physicists assert the detection of novel combinations of quarks in data from Europe’s Large Hadron Collider, unveiling three previously unobserved particles. These include two tetraquarks, comprising four quarks each, and a pentaquark with five quarks, aligning seamlessly with the established Standard Model governing atomic structure.
In a departure from these known particles, scientists anticipate the LHC’s ongoing experiments to reveal clues beyond the Standard Model, elucidating enigmatic phenomena like dark matter. The LHC, revived after a three-year hiatus for system upgrades, now operates at unprecedented energy levels, promising extensive data collection and potential breakthroughs during its four-year Run 3.
This resumption coincides with the 10th anniversary of the Higgs boson discovery, marking a new era in CERN’s quest to uncover the fundamental laws of the Universe. The disclosed exotic hadrons hint at further revelations, reminiscent of the historic era in the 1950s that led to the quark model. The LHCb team’s analysis of negatively charged B mesons reveals a pentaquark and two tetraquarks, expanding our understanding of these rare combinations and their fleeting existence before decay.
The diverse flavors of quarks and the observed combinations challenge theorists to refine models, depicting exotic hadrons as either tightly bound single units or loosely paired structures akin to molecules. Further studies and time will illuminate the true nature of these particles, propelling scientific exploration into the unknown.
