Form factors and other measures of strangeness in the nucleon
M. Diehl, Th. Feldmann, P. Kroll
We discuss the phenomenology of strange-quark dynamics in the nucleon, based on experimental and theoretical results for electroweak form factors and for parton densities. In parti…
Forward-backward and isospin asymmetry for B -> K* l+ l- decay in the standard model and in supersymmetry
Thorsten Feldmann, Joaquim Matias
We discuss two dedicated observables in exclusive B -> K* l+ l- decay that can be used to study effects of physics beyond the standard model, namely the forward-backward asymmetry…
Implications of light-quark admixtures on charmonium decays into meson pairs
Th. Feldmann, P. Kroll
We argue that charmonium decays into meson pairs fall into two distinct classes: one that is under control of perturbative QCD and another one that is governed by a soft mechanism.…
Mixing and Decay Constants of Pseudoscalar Mesons: The Sequel
T. Feldmann, P. Kroll, B. Stech
We present further tests and applications of the new eta-eta' mixing scheme recently proposed by us. The particle states are decomposed into orthonormal basis vectors in a light-co…
Interpolation Formulas for the Eta-Gamma and Eta'-Gamma Transition Form Factors
Thorsten Feldmann, Peter Kroll
The new CLEO and LEP data on the eta-gamma and eta'-gamma transition form factors have renewed the interest in simple interpolation formulas, valid at any value of momentum transfe…
Predictions for the eta_c-gamma transition form factor
T. Feldmann, P. Kroll
The eta_c-gamma transition form factor is calculated in a model based on a modified hard scattering approach to exclusive reactions, in which transverse degrees of freedom are take…
