摘要：
Using the example of selected decays driven by R-parity-violating supersymmetric operators, we demonstrate how strong final-state interactions can be controlled quantitatively with high precision, thus allowing for a more accurate extraction of effective parameters from data. In our examples we focus on the lepton-flavor-violating decays tau -> mu pi(+)pi(-). In R-parity violation these can arise due to the product of two couplings. We find bounds that are an order of magnitude stronger than previous ones.
