Scaling Law for Baryon Coupling to its Current and its possible applications

Abstract

The baryon- coupling to its current (${\lambda }_B$), in conventional QCD sum rule calculations (QCDSR), is shown to scale as the cubic power of the baryon mass, $M_B$. Some theoretical justification for it comes from a simple light-cone model and also general scaling arguments for QCD. But more importantly, taken as a phenomenological ansatz for the present, this may find very good use in current explorations of possible applications of QCDSR to baryon physics both at temperature $T=0$, $T\ne 0$ and/or density $\rho =0$, $\rho \ne 0$.
