摘要：

In the large-N(c) limit, the LAMBDA(b) and LAMBDA(c) can be treated as bound states of chiral solitons and mesons containing a heavy quark. We show that the soliton and heavy meson are bound in an attractive harmonic oscillator potential. The Isgur-Wise function for LAMBDA(b) --> LAMBDA(c)e-nu(e)BAR decay is computed in the large-N(c) limit. Corrections to the form factor which depend on m(N)/m(Q) can be summed exactly (m(N) and m(Q) are the nucleon and heavy quark masses). We find that this symmetry breaking correction at zero recoil is only 1%.
