A quantum exotic hadron is a hadronic state that does not fit the simple quark-antiquark meson or three-quark baryon classification. Examples include tetraquark candidates, pentaquark candidates, molecular hadrons, hybrid mesons, and possible glueballs.[1][2][3]
Structure
Composite hadrons are described by quantum chromodynamics. Their observable properties arise from valence constituents, gluon fields, sea quark-antiquark pairs, orbital motion, and confinement.[4]
Experimental role
Hadrons are reconstructed through masses, lifetimes, decay channels, scattering patterns, and production rates. Their spectra and decays provide detailed tests of strong-interaction dynamics.[5]
