Each relation below ends at this concept.

BaryonProton

Permalink to relation

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

Authored explanation

The proton is the lightest positively charged baryon.

How to interpret this relation type

The target is a member or subtype of the broader source class.

Relation sources

Beta-minus decayProton

Permalink to relation

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

Authored explanation

At the nucleon level, beta-minus decay converts a neutron into a proton.

How to interpret this relation type

A physical process transforms the source into, or produces, the target under the conditions stated in the edge detail.

Relation sources

Gluon gauge fieldProton

Permalink to relation

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

Authored explanation

Gluon fields contribute to proton momentum, interactions, and mass.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

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

Authored explanation

The proton is the positively charged nucleon.

How to interpret this relation type

The target is a member or subtype of the broader source class.

Quark fieldProton

Permalink to relation

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

Authored explanation

The proton is a QCD bound state whose quark-field content has net valence flavor uuduud together with sea-quark and antiquark excitations.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Sea-quark degrees of freedomProton

Permalink to relation

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

Authored explanation

The proton contains sea-quark and antiquark degrees of freedom.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Valence-quark contentProton

Permalink to relation

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

Authored explanation

The proton has net valence flavor uuduud, embedded in a full quark–gluon state.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

ProtonAlpha particle

Permalink to relation

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

Authored explanation

An alpha particle contains two protons.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

ProtonAtomic nucleus

Permalink to relation

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

Authored explanation

Protons are constituent nucleons of nuclei.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

ProtonDeuteron

Permalink to relation

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

Authored explanation

The deuteron contains one proton.

How to interpret this relation type

The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Relation sources

ProtonRutherford proton-transmutation experiment

Permalink to relation

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

Authored explanation

The transmutation experiment established the hydrogen nucleus as a recurring nuclear constituent identified with the proton.

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.
