The decay K+ → π+νν is highly suppressed in the Standard Model (SM), while its rate can be predicted with minimal theoretical uncertainty. The branching ratio (BR) for this decay is thus a sensitive probe of the flavor sector of the SM; its measurement, however, is a significant experimental challenge. The primary goal of the NA62 experiment is to measure BR(K+ → π+νν) with 10% precision. NA62 took data in pilot runs in 2014 and 2015, reaching the design beam intensity. The status of the experiment and the prospects for the measurement of BR(K+ → π+ νν) are presented.

Abstract
The decay K+ → π+νν is highly suppressed in the Standard Model (SM), while its rate can be predicted with minimal theoretical uncertainty. The branching ratio (BR) for this decay is thus a sensitive probe of the flavor sector of the SM; its measurement, however, is a significant experimental challenge. The primary goal of the NA62 experiment is to measure BR(K+ → π+νν) with 10% precision. NA62 took data in pilot runs in 2014 and 2015, reaching the design beam intensity. The status of the experiment and the prospects for the measurement of BR(K+ → π+ νν) are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
