Most of you have not studied the science associated with atoms, molecules, and the like... It would seem as if scientists have found a number sub-atomic particles called quarks... Atoms are made up of electrons, neutrons & protons as scientists have known for some time... Then they found other smaller particles called quarks. But since the commissioning of the Large Hadron Collider at CERN, Switzerland, They have been studying atomic and sub-atomic energy in minute (no, not 'minute' as in seconds, but "minute" as in extremely small, as in size, amount, extent, or degree: minute differences.)
NOTE: The Large Hadron Collider is the world's longest and most powerful particle accelerator, firing beams of subatomic particles around a 17-mile-long (27 kilometers) loop beneath the ground near Geneva, on the French-Swiss border.
From the Video Description I quote the following (LHC = Large Hadron Collider):
"#thecosmosnews Update: LHCb discovers three new exotic particles
The collaboration has observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which includes a new type of tetraquark. The findings, presented today at a CERN seminar, add three new exotic members to the growing list of new hadrons found at the LHC. They will help physicists better understand how quarks bind together into these composite particles.
Quarks are elementary particles and come in six flavours: up, down, charm, strange, top and bottom. They usually combine together in groups of twos and threes to form hadrons such as the protons and neutrons that make up atomic nuclei. More rarely, however, they can also combine into four-quark and five-quark particles, or “tetraquarks” and “pentaquarks”. These exotic hadrons were predicted by theorists at the same time as conventional hadrons, about six decades ago, but only relatively recently, in the past 20 years, have they been observed by LHCb and other experiments.
Most of the exotic hadrons discovered in the past two decades are tetraquarks or pentaquarks containing a charm quark and a charm antiquark, with the remaining two or three quarks being an up, down or strange quark or their antiquarks. But in the past two years, LHCb has discovered different kinds of exotic hadrons. Two years ago, the collaboration discovered a tetraquark made up of two charm quarks and two charm antiquarks, and two “open-charm” tetraquarks consisting of a charm antiquark, an up quark, a down quark and a strange antiquark. And last year it found the first-ever instance of a “double open-charm” tetraquark with two charm quarks and an up and a down antiquark. Open charm means that the particle contains a charm quark without an equivalent antiquark.
The discoveries announced today by the LHCb collaboration include new kinds of exotic hadrons. The first kind, observed in an analysis of “decays” of negatively charged B mesons, is a pentaquark made up of a charm quark and a charm antiquark and an up, a down and a strange quark. It is the first pentaquark found to contain a strange quark. The finding has a whopping statistical significance of 15 standard deviations, far beyond the 5 standard deviations that are required to claim the observation of a particle in particle physics."

I hope that this provides you with another piece of outstanding Scientific News and Education. Enjoy!

Good news, Sgt (Join to see).
New combination of tetraquarks is interesting, isn't it. Apparently, the particles created are identifiable in ways that by their existence, show when tetraquarks have been annihilated!
An organized table is always good. There weren't many to organize even in the early 90s. So many more in only 10 years time, and increasingly more . . . many from LHR.
The work at LHR discounts gravity as "weak" - however gravity can not be removed from the fusion and fission of particles. Plus it is still not clearly identified. Clearly it is not only "weak" as indicated by phase shifts.
