Abstract:
The measurement of the π0 electromagnetic transition form factor (TFF) slope a is performed in the time-like region of momentum transfer using a sample of 1.1 x 106 π0→ e+e-y Dalitz decay collected at the NA62-RK experiment in 2007. The event selection, the fit procedure and the study of the systematic effects are presented. The final result obtained a = (3.68 ± 0.51stat ± 0.25syst) X 10- 2 is the most precise to date and represents the first evidence of a non-zero π0 TFF slope with more than 3σ. The NA62 experiment based at the CERN SPS is currently taking data and aims at measuring the branching fraction of the K→ πvv ultra-rare decay with 10% precision and less than 10% background. A complex trigger and data acquisition system is in place to record the data collected by the various detectors in use to reach this goal. The Run Control system of the experiment is meant to supervise and control them in a simple transparent way. The choices made to address the requirements for the system and the most important aspects of its implementation are discussed.
