A combined study of the pion's static properties and form factors
B. El-Bennich, J. P. B. C. de Melo, T. Frederico
We study consistently the pion's static observables and the elastic and γ*γ-> π^0 transition form factors within a light-front model. Consistency requires that all calculations are…
Pion and kaon elastic form factors in a refined light-front model
Edson O. da Silva, J. P. B. C. de Melo, Bruno El-Bennich +1
Within the framework of light-front field theory, we reassess the electromagnetic form factors of the pion and kaon. Comparison with experiment is made for the full range of moment…
Heavy-quark symmetries in the light of nonperturbative QCD approaches
Bruno El-Bennich, Craig D. Roberts, Mikhail A. Ivanov
We critically review the validity of heavy-quark spin and flavor symmetries in heavy-light decay constants, form factors and effective couplings obtained within a nonperturbative f…
Strong D* -> D+pi and B* -> B+pi couplings
Bruno El-Bennich, Mikhail A. Ivanov, Craig D. Roberts
We compute g_{D* D pi} and g_{B* B pi} using a framework in which all elements are constrained by Dyson-Schwinger equation studies of QCD, and therefore incorporates a consistent,…
