Query: Light-Front Heavy Quark Effective Theory and Heavy Meson Bound States   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 $m_Q\rightarrow\infty$; 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 $\xi(v\cdot v')=1/v\cdot v'$. The slope at the
zero-recoil point is $\rho^2=-\xi'(1)=1$, in excellent agreement with the
recent CLEO result of $\rho^2=1.01\pm0.15\pm0.09$.
