The Belle experiment was a particle physics experiment conducted by the Belle Collaboration, an international collaboration of more than 400 physicists and engineers, at the High Energy Accelerator Research Organisation (KEK) in Tsukuba, Ibaraki Prefecture, Japan.
Exotic hadrons are subatomic particles composed of quarks and gluons, but which do not have the same quark content as ordinary hadrons: exotic baryons differ from the three-quark (qqq) content of ordinary baryons, and exotic mesons differ from the quark-antiquark (q) content of ordinary mesons.
Non-quark model mesons include.
, known as KEK, is a Japanese organization whose purpose is to operate the largest particle physics laboratory in Japan, situated in Tsukuba, Ibaraki prefecture.
The LHCb (standing for "Large Hadron Collider beauty") experiment is one of seven particle physics detector experiments collecting data at the Large Hadron Collider at CERN.
In particle physics, mesons are hadronic subatomic particles composed of one quark and one antiquark, bound together by strong interactions.
In quantum mechanics, a parity transformation (also called parity inversion) is the flip in the sign of one spatial coordinate.
In particle physics, a resonance is the peak located around a certain energy found in differential cross sections of scattering experiments.
In statistical hypothesis testing, a result has statistical significance when it is very unlikely to have occurred given the null hypothesis.
A tetraquark, in particle physics, is an exotic meson composed of four valence quarks.
In quantum mechanics, the total angular momentum quantum number parameterises the total angular momentum of a given particle, by combining its orbital angular momentum and its intrinsic angular momentum (i.e., its spin).
The X(3872) is an exotic meson candidate with a mass of 3871.68 MeV/c2 which does not fit into the quark model because of its quantum numbers.
The Y(4140) particle is an electrically neutral exotic hadron candidate that is about 4.4 times heavier than the proton.
The Zc(3900) is a hadron, a type of subatomic particle made of quarks, believed to be the first tetraquark that has been observed experimentally.
