摘要：

We study the possibility of observing T violation in the process K+ --> pi+ mu+ mu-. To this end we define appropriate T-violation indicators. We find that the measurements of the two-spin correlations can provide a reliable test of the Cabibbo-Kobayashi-Maskawa mechanism of T violation. The final-state interactions mainly contribute to indicators involving only one spin. We also estimate the size of the contribution of a representative set of extensions of the standard model to T-violation indicators. We find that their contribution can be important only in models with loosely constrained new parameters.
