Heavy-quark Baryons as Skyrmions *
نویسنده
چکیده
I discuss recent development on the description of heavy-quark (such as charmed and bottom) baryons as one or more heavy mesons " wrapped " by a skyrmion. Amazingly enough, such a description naturally arises when light-quark chiral symmetry and heavy-quark spin symmetry are incorporated in an effective Lagrangian. I interpret the resulting spectrum in terms of nonabelian induced (Berry) potentials in analogy to diatomic molecular systems.

Heavy Quark Skyrmions
The description of the heavy baryons as heavy-meson–soliton bound systems is reviewed. We outline how such bound systems arise from effective lagrangians that respect both chiral symmetry and heavy quark symmetry. Effects due to finite heavy quark masses are also discussed, and the resulting heavy baryon spectra are compared with existing quark model and empirical results. Finally, we address s...
متن کاملHeavy baryons as Skyrmions with 1/mQ corrections.
We take into account the 1/mQ corrections upto 1/Nc order in the heavymeson-soliton bound state approach for heavy baryons. With these corrections, the mass spectra of baryons with c-quark as well as of those with bquark are well reproduced. For charmed baryons, however, the correction to the mass spectra amounts to about 300 MeV, which is not small compared to the leading order binding energy,...
متن کاملBaryons Containing a Heavy Quark as Solitons ⋆ ( REVISED
The possibility of interpreting baryons containing a single heavy quark as bound states of solitons (that arise in the nonlinear sigma model) and heavy mesons is explored. Particular attention is paid to the parity of the bound states and to the role of heavy quark symmetry. ⋆ Work supported in part by the U.S. Dept. of Energy under Contract no. DEAC-03-81ER40050 and under grant no. DE-FG03-90E...
متن کاملHeavy Quark Fragmentation into Baryons in a Quark-diquark Model
In the framework of the nonrelativistic QCD and a quark-diquark model of baryons we have obtained the fragmentation functions for heavy quark to split into spin-1/2 and spin-3/2 double heavy baryons. It was predicted the production rates as well as the shape of the energy spectra for the cc− and bc−baryons in the region of Zo peak at LEP collider.
متن کاملHEAVY BARYONS: A COMBINED LARGE Nc AND HEAVY QUARK EXPANSION FOR ELECTROWEAK CURRENTS
The combined large Nc and heavy quark limit for baryons containing a single heavy quark is discussed. The combined large Nc and heavy quark expansion of the heavy quark bilinear operators is obtained. In the combined expansion the corrections proportional to mN /mQ are summed to all orders. In particular, the combined expansion can be used to determine semileptonic form factors of heavy baryons...
