A subatomic particle classified as having a non-zero value for strangeness.
〔物理〕奇异粒子
Example sentencesExamples
The model explained this by proposing that the strange particles carry a (slightly unstable) strange quark, while the non-strange particles do not.
We now know that protons and pions are made up of up and down quarks, while these ‘strange particles’ have at least one of a new type of quark that is much like the down quark, only heavier.
One of the huge tasks that the strangeness group is faced with is counting all the strange particles released from the collision.
The enhanced production of strange particles in heavy ion collisions is considered an important signature of the presence of a Quark-Gluon Plasma.
In charmed particle decays, measurements of semileptonic branching ratios imply a much smaller enhancement of nonleptonic modes than in strange particle decays.
