摘要
If new physics (NP) is present in B ->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 ->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.
