Measurement of the η mass at KLOE.

Abstract

An integrated luminosity of 410 pb −1 , corresponding to ∼ 17 million of η events, has been analyzed to measure the η mass using the decay η → γγ. The measurement is insensitive to the calorimeter energy calibration and the systematic error on the measurement is dominated by the uniformity of the detector response. As a cross check of the method the π 0… (More)
