Improving the Hadron Physics of Non-Standard-Model Decays: Example Bounds on R-parity Violation
arXiv:1212.4408 · doi:10.1007/JHEP01(2013)179
Abstract
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.
