The NA62 experiment (known as P-326 at the stage of proposal) is a particle physics experiment in preparation at the North Area of the SPS accelerator at CERN. It aims to start physics data taking in 2014, when it will become the first in the world to probe the decays of the charged kaon with probabilities down to 10−12. The experiment's spokesperson is Augusto Ceccucci.
The experiment is focused on precision tests of the Standard Model by studies of rare decays of charged kaons. The principal goal, for which the design has been optimized, is the measurement of the rate of the ultra-rare decay K+ → π+ + ν + ν with a precision of 10%, by detecting about 100 decay candidates with a low background in two years of data taking. This will lead to the determination of the CKM matrix element |Vtd| with a precision better than 10%. This element relates very accurately the likelihood that top quarks decay to down quarks. The Particle Data Group's 2008 Review of Particle Physics lists |Vtd| = 0.00874+2.6×10−4
