Neutral kaons provide one of the most sensitive systems to CP and CPT violation. Recent results on neutral kaons obtained by the KLOE experiment operating at the DAΦNE ee collider are presented. They include: the first observation of the quantum interference in the channel ϕ→KK→ππππ, the measurements of the main K branching ratios, lifetime and form factor and the measurement of the semileptonic K branching ratio. The latter are used for the determination of V. A direct search of the CP violating K→πππ decay, a preliminary study of the K→πππ decay and the measurement of the branching ratio of the CP violating K→ππ decay are also presented.

Abstract
Neutral kaons provide one of the most sensitive systems to CP and CPT violation. Recent results on neutral kaons obtained by the KLOE experiment operating at the DAΦNE ee collider are presented. They include: the first observation of the quantum interference in the channel ϕ→KK→ππππ, the measurements of the main K branching ratios, lifetime and form factor and the measurement of the semileptonic K branching ratio. The latter are used for the determination of V. A direct search of the CP violating K→πππ decay, a preliminary study of the K→πππ decay and the measurement of the branching ratio of the CP violating K→ππ decay are also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
