We argue that the secondaries produced in high-energy hadron collisions are emitted by small-size sources distributed over a much larger area in impact parameter space occupied by the interaction amplitude. That is, Bose–Einstein correlation of two emitted identical particles should be described by a ‘two-radii’ parametrisation ansatz. We discuss the expected energy, charged multiplicity and transverse momentum of the pair (that is, ) behaviour of both the small and the large size components.
