-
antilepton
the antiparticle of a lepton
-
antiparticle
a particle that has the same mass as another particle but has opposite values for its other properties; interaction of a particle and its antiparticle results in annihilation and the production of radiant energy
-
antiquark
the antiparticle of a quark
-
hadron
any elementary particle that interacts strongly with other particles
-
lepton
an elementary particle that participates in weak interactions; has a baryon number of 0
-
quark
(physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3
-
strange particle
an elementary particle with non-zero strangeness
-
cosmic string, string
(cosmology) a hypothetical one-dimensional subatomic particle having a concentration of energy and the dynamic properties of a flexible loop
-
WIMP, weakly interacting massive particle
a hypothetical subatomic particle of large mass that interacts weakly with ordinary matter through gravitation; postulated as a constituent of the dark matter of the universe
-
antibaryon
the antiparticle of a baryon; a hadron with a baryon number of -1
-
antimeson
the antiparticle of a meson
-
antimuon, positive muon
the antiparticle of a muon; decays to positron and neutrino and antineutrino
-
antineutrino
the antiparticle of a neutrino
-
antitauon, tau-plus particle
an antilepton of very great mass
-
baryon, heavy particle
any of the elementary particles having a mass equal to or greater than that of a proton and that participate in strong interactions; a hadron with a baryon number of +1
-
beauty quark, bottom quark
a quark with a charge of -1/3 and a mass about 10,000 times that of an electron
-
charm quark
a quark with an electric charge of +2/3 and a mass 2900 times that of an electron and a charm of +1
-
down quark
a stable quark with an electric charge of -1/3 and a mass 607 times that of an electron
-
electron, negatron
an elementary particle with negative charge
-
meson, mesotron
an elementary particle responsible for the forces in the atomic nucleus; a hadron with a baryon number of 0
-
mu-meson, muon, negative muon
an elementary particle with a negative charge and a half-life of 2 microsecond; decays to electron and neutrino and antineutrino
-
neutrino
an elementary particle with zero charge and zero mass
-
antielectron, positron
an elementary particle with positive charge; interaction of a positron and an electron results in annihilation
-
squark, strange quark
a quark with an electric charge of -1/3 and a mass 988 times that of an electron and a strangeness of -1
-
tau-minus particle, tauon
a lepton of very great mass
-
top quark, truth quark
a hypothetical quark with a charge of +2/3 and a mass more than 100,000 times that of an electron
-
up quark
a stable quark with an electric charge of +2/3 and a mass 607 times that of an electron
