Kaon Distribution Amplitude from QCD Sum Rules
A. Khodjamirian, Th. Mannel, M. Melcher
We present a new calculation of the first Gegenbauer moment of the kaon light-cone distribution amplitude. This moment is determined by the difference between the average m…

Flavour SU(3) Symmetry in Charmless B Decays
Alexander Khodjamirian, Thomas Mannel, Martin Melcher
QCD sum rules are used to estimate the flavour SU(3)-symmetry violation in two-body B decays to pions and kaons. In the factorizable amplitudes the SU(3)-violation manifests itself…
