文摘

We present a novel method to perform a direct (time reversal) symmetry test in the neutral kaon system, independent of any and/or symmetry tests. This is based on the comparison of suitable transition probabilities, where the required interchange of in ? out states for a given process is obtained exploiting the Einstein-Podolski-Rosen correlations of neutral kaon pairs produced at a ?-factory. In the time distribution between the two decays, we compare a reference transition like the one defined by the time-ordered decays () with the -conjugated one defined by (). With the use of this and other -conjugated comparisons, the KLOE-2 experiment at DA¦µNE could make a statistically significant test.
