Constituent Quark Model Approach to Heavy Baryon Transitions
نویسنده
چکیده
I discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry (HQS) limit as mQ → ∞. By doing a spin-parity analysis I derive a general formula which allows one to enumerate the independent HQS amplitudes in the three types of transitions. I go on to show that use of the constituent quark model for the light-side diquark transitions leads to a considerable reduction in the number of independent amplitudes derived in the HQS limit. The discussion includes the ground state s-wave as well as the p-wave heavy baryons. ∗Supported in part by BMBF,FRG under contract 06MZ566. Invited talk given at the III German-Russian Workshop on Heavy Quark Physics, Dubna, Russia, May 20–22, 1996, to appear in the Proceedings

One-Pion Charm Baryon Transitions in a Relativistic Three-Quark Model
We study one-pion transitions between charm baryon states in the framework of a relativistic three-quark model. We calculate the charm baryon-pion coupling factors that govern the S-wave, P-wave and D-wave one-pion transitions from the s-wave and the lowest lying p-wave charm baryon states down to the s-wave charm baryon states. For these we obtain: gΣcΛcπ=8.88 GeV −1, fΛc1Σcπ=0.52 and fΛc1Σcπ=...
متن کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملCurrent, Pion and Photon Transitions between Heavy Baryons
I discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry limit as mQ → ∞. The emphasis is on the structural similarity of the Heavy Quark Symmetry predictions for the three types of transitions. The discussion involves the ground state s-wave heavy bary...
متن کاملCharmed Baryon Strong Coupling Constants in a Light-Front Quark Model
Light-Front quark model spin wave functions are employed to calculate the three independent couplings gΣcΛcπ, fΛc1Σcπ and fΛc1Σcπ of S-wave to S-wave and P-wave to S-wave one-pion transitions. It is found that gΣcΛcπ = 6.81 MeV , fΛc1Σcπ = 1.16 and fΛc1Σcπ = 0.96 × 10−4 MeV. We also predict decay rates for specific strong transitions of charmed baryons. In the heavy quark limit, the spin and pa...
متن کاملOne – pion transitions between heavy baryons in the constituent quark model
Single pion transitions of S wave to S wave, P wave to S wave and P wave to P wave heavy baryons are analyzed in the framework of the Heavy Quark Symmetry limit (HQS). We then use a constituent quark model picture for the light diquark system with an underlying SU(2Nf ) ⊗ O(3) symmetry to reduce the number of the HQS coupling factors required to describe these transitions. A single constituent ...
