The NA62 Muon Veto system — •Riccardo Aliberti and Letizia Peruzzo — Institut fur Physik Mainz
The ambitious goal of the NA62 experiment is to achieve a direct measurement of the K+ → π+ν$ν$ decay branching ratio with an accuracy around 10This decay has a theoretical BR of 0.85 1010 with a single track detectable: the π+. The main decay channel rates for charged kaons are 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. In order to reduce the background coming from the misidentification of muons as pions, a system of three detectors, called muon veto (MUV 1-2-3), will be used. This talk will present the structure and the state of the construction of the MUV1 detector, which is being built in Mainz.
