On the choice of heavy baryon currents in the relativistic three-quark model
M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij +2
We test the sensitivity of bottom baryon observables with regard to the choice of the interpolating three-quark currents within the relativistic three-quark model. We have found th…
Asymptotic structure of perturbative series for lepton decay observables: corrections
J. G. Koerner, F. Krajewski, A. A. Pivovarov
In a previous paper we performed an analysis of asymptotic structure of perturbation theory series for semileptonic -lepton decays in massless limit. We extend our analysis to t…
Inclusive Decays of B Mesons into D_s and at Including Polarization Effects
M. Fischer, S. Groote, J. G. Körner +1
The dominant contribution to the inclusive decays of mesons into the charm-strangeness mesons and is expected to be given by the partonic process $b \to c+(D…
Lambda_b and Lambda_c baryon decays at finite values of heavy quark masses
M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij +1
Semileptonic decays of Lambda_b and Lambda_c baryons are studied within the Relativistic Three-Quark Model using finite heavy quark mass values. Employing the same parameters as ha…
Asymptotic structure of perturbative series for tau lepton observables
J. G. Koerner, F. Krajewski, A. A. Pivovarov
We analyze tau lepton decay observables, namely moments of the hadronic spectral density in the finite energy interval (0,M_τ), within finite order perturbation theory including α_…
Electromagnetic Transitions of Heavy Baryons in the SU(2N_{f}) X O(3) Symmetry
Salam Tawfiq, J. G. Koerner, Patrick J. O'Donnell
Radiative decays of heavy baryons are analyzed within the Heavy Quark Symmetry (HQS). It is shown that employing the light-diquark symmetries, the number of electromagnetic couplin…
One-pion transitions between heavy baryons in the constituent quark model
F. Hussain, J. G. Koerner, Salam Tawfiq
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 use a con…
Configuration Space Based Recurrence Relations for Sunset-Type Diagrams
S. Groote, J. G. Körner, A. A. Pivovarov
We derive recurrence relations for the calculation of multiloop sunset-type diagrams with large powers of massive propagators. The technique is formulated in configuration space an…
