Muon Pion Separation for the K+ → π+ ν ν Measurement at the NA62 Experiment — •Riccardo Aliberti — Johannes Gutenberg University Mainz
The ambitious goal of the NA62 experiment is to achieve a direct measurement of the K+ → π+ νν branching ratio with an accuracy around 10%. This decay has a theoretical BR of 0.85× 10−10 with a single track detectable: the π+.
The main decay channels of charged kaons have rates several orders of magnitude larger than those for the signal. For this reason the presence of a very efficient veto system to reject background events is mandatory.
The discrimination between muons and pions represents one of the central topics for the measurement of the K+ → π+ νν decay. This talk presents the latest results on the muon pion separation achieved in the NA62 2016 run.
