Symmetries of excited heavy baryons in the heavy-quark and large- N(c) limit
نویسندگان
چکیده
We demonstrate in a model independent way that, in the combined heavy-quark and large- N(c) limit, there exists a new contracted U(4) symmetry which connects orbitally excited heavy baryons to the ground states.

Excited Λ Q Baryons in the Large N c Limit ⋆
The spectrum of excited ΛQ-type heavy baryons is considered in the largeNc limit. The universal form factors for Λb semileptonic decay to excited charmed baryons are calculated in the large Nc limit. We find that the Bjorken sum rule (for the slope of the Isgur–Wise function) and Voloshin sum rule (for the mass of the light degrees of freedom) are saturated by the first doublet of excited ΛQ st...
متن کاملExcited heavy baryon spectrum in large N c heavy quark effective theory
L = 1 excited heavy baryon masses are analyzed by heavy quark and large Nc expansions. In heavy quark limit, mass is parameterized by Λ̄ and it is expanded further by spin-flavor breaking operators to the zeroth order of 1/Nc. Expanding coefficients will be fixed by more data on the excited baryons in the near future. Typeset using REVTEX Email address: [email protected] Email address: liuc@c...
متن کاملJHU{TIPAC{96007 hep-ph/9603389 A New Interpretation of the Observed Heavy Baryons
I suggest that the conventional assignment of quantum numbers to the observed charm and bottom baryons is not correct, as these assignments imply large violation of the heavy spinavor and light SU(3) symmetries. I propose an alternative interpretation of the observed states, in which the symmetries are preserved. If these novel assignments are right, there is a new state with mass approximately...
متن کاملCharm and bottom baryon masses in the 1/N expansion
The 1/Nc expansion has proven useful for studying the spin-flavor properties of baryons containing light quarks. A spin-flavor symmetry for baryons is defined in large-Nc QCD. Away from the Nc → ∞ limit, 1/Nc corrections which break large-Nc baryon spin-flavor symmetry can be classified in terms of the spin and flavor symmetries which remain for finite Nc. Since explicit SU(3) flavor symmetry b...
متن کاملHadrons of Arbitrary Spin and Heavy Quark Symmetry
We present a general construction of the spin content of the BetheSalpeter amplitudes (covariant wave functions) for heavy hadrons with arbitrary orbital excitations, using representations of L ⊗ O(3, 1). These wave functions incorporate the symmetries manifest in the heavy quark limit. In the baryonic sector we clearly differentiate between the Λ and Σ-type excited baryons. We then use the tra...
