J/ψ meson
E1551122
UNEXPLORED
The J/ψ meson is a bound state of a charm quark and its antiquark whose 1974 discovery marked the beginning of the "November Revolution" and confirmed the existence of the charm quark.

How this entity was disambiguated
This entity first appeared as the object of triple T22695988 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: J/ψ meson Context triple: [Samuel C. C. Ting, discovered, J/ψ meson]
-
A.
Υ(4S) resonance
The Υ(4S) resonance is an excited bottomonium state that lies just above the threshold for B-meson pair production and is widely used at B-factories to study B-meson decays and CP violation.
-
B.
Z boson
The Z boson is a neutral elementary particle that mediates the weak nuclear force and plays a central role in the electroweak theory of particle physics.
-
C.
K0 meson
The K0 meson is a neutral kaon, a short-lived subatomic particle containing a strange quark and a down antiquark, notable for its role in studies of CP violation in weak interactions.
-
D.
X boson
The X boson is a hypothetical heavy gauge boson proposed in grand unified theories that would mediate interactions causing proton decay and unify the electromagnetic, weak, and strong forces at high energies.
-
E.
W boson
The W boson is a massive elementary particle that mediates the weak nuclear force and is responsible for processes like beta decay in the Standard Model of particle physics.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
