چکیده
The Isgur-Wise functions for the ground state to ground state semileptonic decays involving b → c transitions are calculated from the (modified) MIT bag model. It is checked that the results for the decays B → Dlν and B → D * lν agree well with experiment. Predictions for the decays Λ b → Λ c lν, B s → D s lν and B s → D * s lν are given and discussed.

Covariant and heavy quark symmetric quark models.
There exist relativistic quark models (potential or MIT-bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. Covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions. Proton form factor and M1 transitions in quarkonia are calculated. Explicit expression for the Isgur-Wise...
متن کاملSemileptonic Decays of Bottom and Charm Baryons within Relativistic Quark Model
The last few years have brought rapid development of the physics of hadrons composed of light quarks q (u, d and s) and heavy quarks Q (c or b). Heavy quarks are those whose masses satisfy the conditionmQ ≫ ΛQCD, where ΛQCD is the QCD scale parameter. Weak decays of heavy hadrons are a unique tool for determining the elements of the Cabibbo-Kobayashi-Maskawa matrix, for studying phenomena lying...

In quark modelsà la Bakamjian and Thomas, that yield covariance and Isgur-Wise scaling of form factors in the heavy quark limit, we compute the decay constants f (n) and f (n) 1/2 of S-wave and P-wave mesons composed of heavy and light quarks. Heavy quark limit scaling √ M f = Cst. is obtained, and it is shown that this class of models satisfies the sum rules involving decay constants and Isgur...

The spin-dependent structure functions g 1 (x), g 2 (x), g W W 2 (x) and ¯ g 2 (x) and their moments are studied in the CM bag model. The results show that (i) 1 0 g 2 (x)dx = 0, i.e. the Burkhardt-Cottingham sum rule holds, hence g 2 (x) must have at least one non-trivial zero besides x = 0 and x = 1. 1 0 x 2 g 2 (x)dx is negative for the proton, neutron and deuteron. (iii) 1 0 x 2 g 2 (x)dx i...
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 .
