Factorization property of the deuteron
Abstract
Using a simple field-theoretic model we show that, in the zero-binding limit, the relativistic deuteron wave function has a cluster decomposition; i.e., it factors into two separate nucleon wave functions convoluted with a body wave function. The framework of the calculation is a Fock-state expansion at equal time on the light cone. Assuming a quark-interchange mechanism, we then derive the deuteron reduced form factor at large momentum transfer, while recovering the standard impulse-approximation form at small momentum transfer.
