Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The J/ψJ/\psi spectrum established a charm–anticharm bound state and the charm flavor.

How to interpret this relation type

The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
