摘要

The heavy-quark effective theory is developed on the light front. Based on this effective theory, a light-front heavy-meson bound state with definite spin and parity is constructed. Within the effective theory, the Isgur-Wise function is derived in terms of the asymptotic light-front bound state amplitudes in the limit mQ; the result is a general expression for arbitrary recoil velocities. With the asymptotic form of the BSW amplitudes, the Isgur-Wise function is given by (vv)=1/vv. The slope at the zero-recoil point is 2=-(1)=1, in excellent agreement with the recent CLEO result of 2=1.010.150.09.
