Three subatomic particles discovered by researchers working with the Large Hadron Collider (LHC) have been previously unknown as they strive to uncover the universe's building blocks, according to CERN, a European nuclear research center.
The 27 kilometer (16.8 mile) LHC at CERN is the machine that discovered the Higgs boson particle, which is believed to be vital to the universe's formation after the Big Bang 13.7 billion years ago.
Scientists at CERN have discovered a new type of pentaquark and the first-ever pair of tetraquarks, extending the number of new hadrons discovered at the LHC.
They will assist physicists in understanding how quarks bond together into composite particles.
Quarks are elementary particles that combine in groups of twos and threes to form hadrons, such as the protons and neutrons that make up nuclear nuclei.
However, they may also form four-quark and five-quark particles, or tetraquarks and pentaquarks, less frequently.
Niels Tuning, a physicist, said in a statement that the more analyses we perform, the more kinds of exotic hadrons we discover.
When a particle zoo of hadrons began being discovered and ultimately led to the quark model of conventional hadrons in the 1960s, we were witnessing a period of discovery similar to the 1950s. Were we creating particle zoo 2.0?
The Large Hadron Collider is about to start smashing protons together at unprecedented energy levels in its quest to reveal additional secrets about how the universe works.
After a three-year hiatus for upgrades in preparation for its third run, the world's largest and most powerful particle collider recommenced in April.
At a press briefing last week, the European Organization for Nuclear Research (CERN) declared that the system would run around the clock for nearly four years starting on Tuesday.
