Mesonic Form Factors in the Light-front Quark Model
نویسنده
چکیده
Form factors for P → P and P → V transitions due to the valence-quark configuration are calculated directly in the physical time-like range of momentum transfer within the light-front quark model. It is pointed out that the Bauer-Stech-Wirbel type of light-front wave function fails to give a correct normalization for the IsgurWise function at zero recoil in P → V transition. Some of the P → V form factors are found to depend on the recoiling direction of the daughter mesons relative to their parents. Thus, the inclusion of the non-valence contribution arising from quark-pair creation is mandatory in order to ensure that the physical form factors are independent of the recoiling direction.

Mesonic Tensor Form Factors with Light Front Quark Model
We study the tensor form factors for P → P and P → V transitions in the lightfront quark model with P and V being pseudoscalar and vector mesons, respectively. We explore the behaviors of these form factors in the entire physical range of 0 ≤ p ≤ (Mi−Mf ). At the maximum recoil of p = 0, we compare our results of the form factors in B → π,K, ρ,K with various other calculations in the literature.
متن کاملMesonic Form Factors and the Isgur-Wise Function on the Light-Front
Within the light-front framework, form factors for P → P and P → V transitions (P : pseudoscalar meson, V : vector meson) due to the valence-quark configuration are calculated directly in the entire physical range of momentum transfer. The behavior of the form factors in the infinite quark mass limit are examined to see if the requirements of heavy-quark symmetry are fulfilled. We find that the...
متن کاملA Constituent Quark-Meson Model for Heavy-Meson Processes
We describe the effective heavy meson lagrangian for Sand P-wave heavy-light mesons in terms of a model based on meson-quark interactions, where mesonic transition amplitudes are represented by diagrams with heavy mesons attached to loops containing heavy and light constituent quarks. The model is relativistic and incorporates the heavy quark symmetries. The universal form factors of the heavy ...
متن کاملIsgur-wise Form Factors of Heavy Baryons within a Light-front Constituent Quark Model
The space-like elastic form factors of baryons containing a heavy quark are investigated within a light-front constituent quark model in the limit of infinite heavy-quark mass, adopting a gaussian-like ansätz for the three-quark wave function. The results obtained for the Isgur-Wise form factors corresponding both to a spin-0 and a spin-1 light spectator pair are presented. It is found that the...
متن کاملCharge and Transition Form Factors of Light Mesons with Light-Front Quark Model
The charge and transition form factors of pion (Fπ, Fπγ , and Fπγ∗) are studied with the light-front quark model. We find that our results for Fπ and Fπγ agree very well with experimental data. Furthermore, the decay constants of η and η are evaluated. We also calculate Fηγ and Fη′γ and compare with the experimental data. PACS numbers: 12.39.Ki, 13.40.Gp Typeset using REVTEX
