The NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient minimum bias trigger for decays into electrons in 2007. The kaon beam represents a source of tagged neutral pion decays in vacuum. A preliminary result of a new measurement of the electromagnetic transition form factor slope of the neutral pion in the time-like momentum region from ∼ 1 million fully reconstructed (π0) Dalitz decays is presented.

Abstract
The NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient minimum bias trigger for decays into electrons in 2007. The kaon beam represents a source of tagged neutral pion decays in vacuum. A preliminary result of a new measurement of the electromagnetic transition form factor slope of the neutral pion in the time-like momentum region from ∼ 1 million fully reconstructed (π0) Dalitz decays is presented.File in questo prodotto:
