Description
The flavour-changing neutral current decays B -> K^(*) l^+ l^- and B -> K^* gamma have a complicated dynamics, with an interplay of short-distance electroweak/QCD and long-distance hadronic effects. I will discuss the hadronic input needed for an accurate description of decay observables. This includes the B -> K^(*) form factors and nonlocal hadronic matrix elements generated by the four-quark and penguin operators. Non-lattice QCD calculations of the form factors and nonlocal hadronic effects will be overviewed.
