Rare exclusive semileptonic b -> s transitions in the Standard Model
D. Melikhov, N. Nikitin, S. Simula
We study long-distance effects in rare exclusive semileptonic decays B -> (K, K*) (l+ l-, nu bar{nu}) and analyze dilepton spectra and asymmetries within the framework of the Stand…
Dispersion Quark Model of Heavy Meson Decays
Dmitri Melikhov
We discuss applications of the dispersion quark model to exclusive semileptonic decays of heavy mesons. The transition form factors in this relativistic formulation of the quark mo…
Heavy quark expansion and universal form factors in quark model
Dmitri Melikhov
Meson transition amplitudes of the vector, axial-vector, and tensor quark currents are analyzed within dispersion formulation of the constituent quark model. The form factors in th…
Long-distance contribution to exclusive rare decays of heavy mesons in quark model
Dmitri Melikhov
Nonperturbative effects in exclusive reactions are discussed. Form factors which describe the main long-distance contribution to the meson transition amplitude are…
η-η' -Glueball mixing from photon-meson transition form factors and decay ratio D_s --> ηl ν/ η' l ν
V. V. Anisovich, D. V. Bugg, D. I. Melikhov +1
The background due to the direct diffractive dissociation of the photon into the -pair to the "elastic" diffractive -meson production in electron-proton collisions is…
