description

If new physics (NP) is present in B{yields}{pi}{pi} decays, it can affect the isospin I=2 or I=0 channels. In this paper, we discuss various methods for detecting and measuring this NP. The techniques have increasing amounts of theoretical hadronic input. If NP is eventually detected in B{yields}{pi}{pi}--there is no evidence for it at present--one will be able to distinguish I=2 and I=0, and measure its parameters, using these methods.
