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.
