Direct test of time-reversal symmetry in the entangled neutral kaon system at a \phi-factory

We present a novel method to perform a direct T (time reversal) symmetry test in the neutral kaon system, independent of any CP and/or CPT symmetry tests. This is based on the comparison of suitable transition probabilities, where the required interchange of in <-> out states for a given proce...

description We present a novel method to perform a direct T (time reversal) symmetry test in the neutral kaon system, independent of any CP and/or CPT 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-Podolsky-Rosen correlations of neutral kaon pairs produced at a \phi-factory. In the time distribution between the two decays, we compare a reference transition like the one defined by the time ordered decays (l^-,\pi\pi) with the T -conjugated one defined by (3\pi^0, l^+). With the use of this and other T conjugated comparisons, the KLOE-2 experiment at DAFNE could make a significant test.

In the time distribution between the two decays, we compare a reference transition like the one defined by the time-ordered decays ( ℓ−,ππ ) with the T -conjugated one defined by ( 3π0,ℓ+ ). With the use of this and other T -conjugated comparisons, the KLOE-2 experiment at DAΦNE could make a statistically significant test.We present a novel method to perform a direct T (time reversal) symmetry test in the neutral kaon system, independent of any CP and/or CPT 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-Podolsky-Rosen correlations of neutral kaon pairs produced at a $\phi$-factory. In the time distribution between the two decays, we compare a reference transition like the one defined by the time ordered decays $(\ell^-,\pi\pi)$ with the T -conjugated one defined by $(3\pi^0, \ell^+)$. With the use of this and other T conjugated comparisons, the KLOE-2 experiment at DA$\Phi$NE could make a significant test.arXiv:1208.0773oai:cds.cern.ch:14717302012-08-06
