摘要

The eta(c)(1S)-> PP' decays are the parity violation modes. These decays can be induced by the weak interactions within the standard model, and have been searched for based on the available experimental data. To meet the needs of experimental investigation, the eta(c)(1S)-> PP' decays are studied with the perturbative QCD approach. It is found that branching ratios are the order of 10(-15) and less, which offers a ready reference for future analyses.
