Meaning and Definition
A type of subatomic particle, specifically a meson containing a charm quark and an anti-charm quark (also called a J/psi meson).
In particle physics, a short-lived elementary particle belonging to the meson family, significant for its role in confirming the quark model and the existence of the charm quark. Its discovery in 1974 was a landmark event.

FAQ
Frequently Asked Questions
Yes, these terms refer to the same particle. The dual name commemorates its nearly simultaneous independent discovery by Burton Richter (who named it 'psi') and Samuel Ting (who named it 'J').
It provided the first direct evidence for the existence of the charm quark, a key prediction of the quark model, and helped establish the Standard Model of particle physics.
No. Chi mesons are subatomic particles that exist for only a fraction of a second. They are detected indirectly through the patterns of decay products in particle accelerators like the Large Hadron Collider.
Not directly in everyday technology. However, the research leading to its discovery and the techniques developed for particle detection have contributed to advances in medical imaging, computing, and materials science.
