Scientists from Tel Aviv University in Israel and the University of Chicago in the United States have proven that quarks can release powerful energy in a fusion reaction, and their power is even greater. Much more so than nuclear fusion produces hydrogen bombs that release energy. But the researchers say that the quark will decay in 1 pico second (1 pico second = 0.001 nanoseconds), so people don’t have to worry about it being used in weapons.
Quarks are a kind of elementary elementary particle and a basic constituent of matter. The quarks combine to form composite particles called hadrons, with the most stable particles being protons and neutrons – the constituent particles of atomic nuclei. Due to an effect called color confinement, quarks are never found standing alone; they can only be found within hadrons.
Quarks are particles that make up subatomic particles such as neutrons and protons. There are currently six main types of particles discovered: up quark, down quark, top quark, bottom quark, strange quark and charm quark. Among them, only the top and bottom quarks have the largest mass. Their light is the most stable and can be found in the universe, while other particles can only be generated through high-energy collisions.
In June 2017, the CERN team discovered that a new baryon (also known as the fermion baryon are semi-intact spin hadrons containing 3 valence quarks and 3 valence antiquarks) containing two new charm quarks from the data. high energy collision. Scientists at the time speculated that predestined quarks could release excess energy into the universe by recombining into baryons.
The quark model was proposed independently by physicists Murray Gell-Mann and George Zweig in 1964. The quarks are given as part of the arrangement diagram for hadrons, and there is little evidence of their existence until 1968. All six quarks have been observed in experimental accelerators, the last discovered quark observed at Fermilab in 1995.
In the latest study, Marek Karine of Tel Aviv University and Jonathan Rosner of the University of Chicago theoretically calculated that the two charm quarks will release 12MeV (megaelectron volts) in the fusion reaction, which equals about 2/3 of the energy comes from fusion reaction (18MeV). The fusion of the two bottom quarks can even release a powerful energy source of 138 meV.
However, the researchers said, in an atomic bomb, a single fusion reaction does not pose a danger, it gains strength by accumulating large amounts of deuterium and tritium to induce wire fusion. pass.
After the quark is produced, it will decay into ordinary particles with lower energies within 1 pico second and cannot accumulate or store to cause a chain reaction. This new research will open up a whole new realm of particle physics. Over the next two years, CERN’s Large Hadron collider will be able to perform similar experiments to verify the true potential of quark fusion.
