Charmed decays of the B-meson in the quark model
I. L. Grach, I. M. Narodetskii, K. A. Ter-Martirosyan +1
Exclusive and inclusive, semileptonic and non-leptonic, charmed decays of the B-meson are investigated in the context of a phenomenological quark model. Bound-state effects are tak…
Weak Decay Form Factors of Heavy Pseudoscalar Mesons within a Light-Front Constituent Quark Model
I. L. Grach, I. M. Narodetskii, S. Simula
The transition form factors describing the semileptonic decays of heavy pseudoscalar mesons are investigated within a relativistic constituent quark model formulated on the light-f…
Exclusive and inclusive weak decays of the B-meson
I. L. Grach, I. M. Narodetskii, S. Simula +1
A relativistic quark model is applied to the description of semileptonic and non-leptonic charmed decays of the B-meson. The exclusive semileptonic modes B -> D l νand B -> D* l νa…
Heavy-to-heavy and heavy-to-light weak decay form factors in the light-front approach: the exclusive to case
N. B. Demchuk, I. L. Grach, I. M. Narodetski +1
Weak transition form factors among heavy pseudoscalar mesons are investigated within a relativistic quark model formulated on the light-front. It is shown that the light-front resu…
Electromagnetic Structure of Mesons in a Light-Front Constituent Quark Model
F. Cardarelli, I. L. Grach, I. M. Narodetskii +2
The elastic and transition electromagnetic form factors of mesons are investigated within a light-front constituent quark model. The general formulae for the space-like matrix elem…
Radiative and transition form factors in a light-front constituent quark model
F. Cardarelli, I. Grach, I. Narodetskii +2
The form factors of the and radiative transitions are evaluated within a light-front constituent quark model, using for the first time the eigenfunctions of a light-front…
