Large N C Universality of the Baryon Isgur{wise Form Factor: the Group Theoretical Approach Typeset Using Revt E X
نویسنده
چکیده
In a previous article, it has been proved under the framework of chiral soliton model that the same Isgur{Wise form factor describes the semileptonic b ! c and () b ! () c decays in the large N c limit. It is shown here that this result is in fact independent of the chiral soliton model and is solely the consequence of the spin-avor SU(4) symmetry which arises in the baryon sector in the large N c limit.

A Systematic Study of Heavy Exotics in the Large N C Limit Typeset Using Revt E X 1
A systematic study of multiquark exotics with one or Nc − 1 heavy quarks in the large Nc limit is presented. By binding a chiral soliton to a heavy meson, either a normal Nc-quark baryon or an exotic (Nc + 2)-quark baryon is obtained. By replacing the heavy quark with Nc−1 heavy antiquarks, exotic (2Nc− 2)-quark and 2Nc-quark mesons are obtained. When Nc = 3, they are just the normal triquark b...

متن کامل1/Nc Expansion of the Heavy Baryon Isgur-Wise Functions
The 1/Nc expansion of the heavy baryon Isgur-Wise functions is discussed. Because of the contracted SU(2Nf) light quark spin-flavor symmetry, the universality relations among the Isgur-Wise functions of Λb → Λc and Σ (∗) b → Σ (∗) c are valid up to the order of 1/N 2 c .

In the largeNc limit, the Λb and Λc 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 Λb → Λc e νe decay is computed in the large Nc limit. Corrections to the form factor which depend on mN/mQ can be summed exactly (mN and mQ are the...
