CP- and T-Violation in the Decay KL → π + π − e + e − and Related Processes ∗

by L. M. Sehgal , 1999
"... I review the theoretical basis of the prediction that the decay KL → π + π − e + e − should show a large CP- and T-violation, a prediction now confirmed by the KTeV experiment. The genesis of the effect lies in a large violation of CP- and T-invariance in the decay KL → π + π − γ, which is encrypted ..."

is encrypted in the polarization state of the photon. The decay KL → π + π − e + e − serves as an analyser of the photon polarization. The asymmetry in the distribution of the angle φ between the π + π − and e + e − planes is a direct measure of the CP-odd, T-odd component of the photon’s Stokes vector. A

"... TREK is a precision-frontier experiment, planned at J-PARC (Tokai, Japan), for a T-violation search in kaon decays into the pi0µ+ν final state. The signature is a non-zero transverse polariza-tion (PT) of muons in the direction perpendicular to the decay plane. Using the same process the E246 experi ..."

SEARCH FOR T-VIOLATION in Kµ3 DECAY BNL-65154

"... We have designed a new experiment (E923) at the BNL-AGS to search for the T-violating polarization of the muon normal to the decay plane of the K + → µ + π 0 ν decay. The experiment aims to search for T-violation beyond the Standard Model; such a search is motivated by the need for a stronger CP vio ..."

1 Large Effects of CP- and T-Violation in K 0 Decay

by L. M. Sehgal , 2000
"... The ǫ-impurity of the KL wave-function gives rise to a huge CP-violating effect in the decay KL → π + π − γ which is hidden in the polarization state (Stokes vector) of the photon. One component of the Stokes vector is CP-odd and T-even, and may be identified with circular polarization. Another comp ..."

RESULT OF T-VIOLATING MUON POLARIZATION MEASUREMENT IN THE K + → π 0 µ + ν DECAY

by J. Imazato , 2004
"... A search for T-violating muon polarization in the K + → π 0 µ + ν decay has been performed at KEK using stopped kaons. A new improved limit was obtained, PT = −0.0017±0.0023(stat)± 0.0011(syst), corresponding to a 90 % confidence limit of |PT | < 0.0050. The T-violating parameter was also determi ..."

This polarization is defined as the component of the muon polarization perpendicular to the decay plane, namely PT = sµ · (pπ × pµ)/|pπ × pµ|, and its non-zero value is a clear signature of T-violation with T-odd character because of the negligible level of any spurious final

PHENOMENON OF THE TIME-REVERSAL-VIOLATING PHOTON POLARIZATION PLANE ROTATION BY A GAS PLACED TO AN ELECTRIC FIELD

by unknown authors , 1998
"... many years ago [1], and remains one of the great unsolved problems in elementary particle physics. Since the discovery of the CP-violation in decay of K0-mesons, a few attempts have been undertaken to observe this phenomenon experimentally in different processes. However, that experiments have not b ..."

According to [6] the violation of the time reversal symmetry stipulates the appearance of the new optical phenomenon: the photon polarization plane rotation and circular dichroism in an optical homogeneous isotropic matter placed to an electric field. This T-odd phenomenon is the kinematic
