Abstract
The penguin amplitude receives contributions from internal , and -quarks. We show that it is impossible to measure the weak phase of any of these penguin contributions without theoretical input. However, a single assumption involving the hadronic parameters makes it possible to obtain the weak phase and test for the presence of new physics in the flavour-changing neutral current.
