Meeeeh I'm not a big fan of particles but this is awesome news:
Scientists on the DZero collaboration at the U.S. Department of Energy's Fermilab have discovered a new particle.
The newly-discovered tetraquark particle X(5568), named for its mass 5568 MeV, contains 4 distinct flavors – bottom, strange, up and down.
X(5568) decays via the strong interaction into a Bs0 and pi+ mesons. The Bs0 meson decays into a J/psi and a phi meson, and these in turn decay into 2 muons and 2 kaons, respectively.
DZero looks so fucking big and badass
The next question will be to understand how the four quarks are put together. And perhaps the emerging tetraquark species will become an established class in the future, showing themselves to be as numerous as their two- and three-quark siblings.
Anywho congrats Fermilab scientists! Well Done!!!
edit:
Scientists are investigating the internal structure of X(5568). Its four quarks could be configured as on the left – a tetraquark. It could also be configured as two pairs in a so-called molecular state, similar to a molecule of hydrogen, in which the two hydrogen atoms circle each other.
