proton's existence and structure are supposed to be described by quantum chromodynamics …

Colloquium: Roper resonance: Toward a solution to the fifty year puzzle

VD Burkert, CD Roberts - Reviews of Modern Physics, 2019 - APS
Discovered in 1963, the Roper resonance appears to be an exact copy of the proton except
