Hadron spectra for semileptonic heavy quark decay.
We calculate the leading perturbative and power corrections to the hadronic invariant mass and energy spectra in semileptonic heavy hadron decays. We apply our results to the B system. Moments of the invariant mass spectrum, which vanish in the parton model, probe gluon bremsstrahlung and nonperturbative effects. Combining our results with recent data on B meson branching ratios, we obtain a lo...
متن کاملDoubly heavy quark baryon spectroscopy and semileptonic decay
Working in the framework of a nonrelativistic quark model we evaluate the spectra and semileptonic decay widths for the ground state of doubly heavy Ξ and Ω baryons. We solve the three-body problem using a variational ansatz made possible by the constraints imposed by heavy quark spin symmetry. In order to check the dependence of our results on the inter-quark interaction we have used five diff...
متن کاملRadiative and Semileptonic B Meson Decay Spectra
We review semi-inclusive charmless B decays, focussing on threshold logarithmic resumming and on universality of QCD dynamics in radiative and semileptonic decays. e-mail address: [email protected] 1 Semileptonic B decays The precise determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) element Vub with a clear uncertainty remains one of the key goals of the heavy flav...
متن کاملSemileptonic baryon decays with a heavy quark.
The semileptonic decay of spin-l/2 baryons is examined in the spectator quarkmodel, with special attention given to Ab + A,ev and nb + &ev. The polarization of the virtual-W and of the daughter baryon is also considered, along with the joint angular distribution between the charged lepton and the daughter baryon polarization vector. The Ab decays with about equal mixtures of transverseto longit...
متن کاملB-hadron production in top quark decay
We present the energy distribution of b-flavoured hadrons in top quark decay using the PYTHIA and HERWIG event generators, which we tune to LEP and SLD data. We find that fitting the string and cluster models is essential to reproduce the ee data and to reliably predict B-hadron production in top decay. We also compare the PYTHIA and HERWIG results with the ones yielded by resummed calculations...
