Hadronic form factors from light-cone sum rules
Alexander Khodjamirian (Siegen)
I will overview the recent progress and challenges in calculating the hadronic form factors at large recoil, employing the QCD sum rules on the light-cone. This non-lattice method is being applied to a broad variety of hadronic transition matrix elements: from the pion electromagnetic form factors to the exclusive b → u transitions. The latter are used for the Vub determination, where the issue of accuracy remains vitally important.
