Successful commissioning of the NA62 detector systems

Preparation for collecting 100 events of the rare decay

Optimistic outlook for 2015 data-taking and measurement precision

Abstract

The main purpose of the NA62 experiment is to measure the branching ratio of the (ultra) rare decay $K+ \rightarrow {\pi}+{\nu}\bar{\nu}$ with the precision of 10% collecting about 100 events with the Standard Model branching fraction in 3 years of data taking. The commissioning of the experiment after the 2014 pilot run and the prospects for the 2015 run are presented.
