The NA62 experiment at CERN SPS aims to measure the branching ratio of the ultra-rare kaon decay K+ ⇒ π+vv with 10% precision, collecting ∼ 100 events, assuming the Standard Model (SM) branching ratio of 8.4 × 10-11, starting in 2016. The NA62 experiment uses a kaon decay-in-flight technique and is exposed to a 750 MHz high-energy unseparated charged hadron beam, in which kaons are a minor component (6%). Kaon identification is therefore mandatory to reduce the interference of the dominant non-kaon component with the experimental measurements. The NA62 kaon identification system and its performances are presented.

Abstract
The NA62 experiment at CERN SPS aims to measure the branching ratio of the ultra-rare kaon decay K+ ⇒ π+vv with 10% precision, collecting ∼ 100 events, assuming the Standard Model (SM) branching ratio of 8.4 × 10-11, starting in 2016. The NA62 experiment uses a kaon decay-in-flight technique and is exposed to a 750 MHz high-energy unseparated charged hadron beam, in which kaons are a minor component (6%). Kaon identification is therefore mandatory to reduce the interference of the dominant non-kaon component with the experimental measurements. The NA62 kaon identification system and its performances are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
