WebThe dead-cone effect is predicted in quantum chromodynamics — the theory of strong interactions — but has never been observed directly. A direct observation of the dead-cone effect in QCD is challenging since its observation requires the reconstruction of the cascading quarks and gluons from the experimentally accessible hadrons.
