The NA62 Experiment — •Gia Khoriauli — Johannes Gutenberg-Universität Mainz, Mainz, Deutschland

NA62 is a fixed target experiment at CERN operating on the 400 GeV proton beam supplied by the CERN SPS accelerator facility. The main physics goal of the experiment is to perform a very precise measurement of the kaon rare decay K⁺ → π⁺νν. This particular decay channel is strongly suppressed in the Standard Model but on the other hand its rate can be calculated with high accuracy. The NA62 is designed to measure the K⁺ → π⁺νν decay rate with an uncertainty of a couple of percents. Therefore, any significant disagreement between the theoretically calculated and measured decay rate can serve as a clear evidence of some new physics phenomena. The experiment has been launched in October 2014. We review the performance of the NA62 sub-detectors and the first physics results. Main accents will be made on the contribution of the NA62 working group of the University of Mainz.
