A new KS → πeν branching fraction measurement from KLOE-2

The KLOE-2 Collaboration continues the KLOE long-standing tradition of flavour physics precision measurements in the kaon sector with a new KS → πeν branching fraction measurement with 1.63 fb−1 KLOE data acquired at the DAΦNE Frascati ϕ-factory.

Summary:The KLOE-2 Collaboration continues the KLOE long-standing tradition of flavour physics precision measurements in the kaon sector with a new KS → πeν branching fraction measurement with 1.63 fb−1 KLOE data acquired at the DAΦNE Frascati ϕ-factory. The strategy to achieve this new result has been presented together with the combination with our previous BR(KS → πeν) measurement, based on an independent data sample, which allows the total precision to be improved by almost a factor of two, and a new derivation of f+(0)|Vus|.
