Polarization effects in the cascade decay Lambda(b) -> Lambda(-> p pi(-)) + J/psi(-> l(+)l(-)) in the covariant confined quark model

Autor: T. Gutsche, M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij, SANTORELLI, PIETRO

We calculate the invariant and helicity amplitudes for the nonleptonic decay Lambda(b) -> Lambda + J/psi, psi(2S) in the covariant confined quark model. We discuss joint angular decay distributions in the cascade decay Lambda(b) -> Lambda(-> p pi(-))

Semileptonic and nonleptonic decays of B-c

Autor: M. A. Ivanov, J. G. Korner, SANTORELLI, PIETRO

Using our relativistic constituent quark model we present results on the exclusive nonleptonic and semileptonic decays of the B-c-meson. The nonleptonic decays are studied in the framework of the factorization approximation. We calculate the branchin

On the corrections to the form-factors in decays

Autor: D. Pirjol, J. G. Korner

Publikováno v: Physics Letters B. 334:399-404

Model-independent bounds are presented for the form-factors describing the semileptonic decay $\Lambda_b\to\Lambda_ce\bar\nu_e$ at the end-point of the lepton energy spectrum. For the axial-vector form-factor $f_1^A(1)$ we obtain $f_1^A(1)\leq 0.960\

The Semileptonic decays of the B(c) meson

Autor: Ivanov, M. A., Korner, J. G., Santorelli, P.

We study the semileptonic transitions B_c to \eta_c, J/\psi, D, D^*, B, B^*, B_s, B_s^* in the framework of a relativistic constituent quark model. We use experimental data on leptonic J/\psi decay, lattice and QCD sum rule results on leptonic B_c de
