文摘

The NA48/2 experiment at CERN [V. Fanti et al., Nucl. Instrum. Meth. A574 433-471 (2007).] collected charged kaon decays during the years 2003/4. Along with the primary goals of the collaboration, i.e., the measurement of the CP-violating asymmetry in the and channels, the collected data allowed to perform many other interesting analyses. In this paper the measurement of the and decays? branching ratios (BR) and form factors will be reviewed.
