Meson transition form factors at KLOE/KLOE-2
In this work we present a study of the Dalitz decay ϕ → ηe+e−, with η → π0π0π0, performed using 1.7 fb−1 of e+e− collisions collected at KLOE in the 2004-2005 data taking period. The resulting branching fraction is: BR(ϕ → ηe+e−) = (1.059 ± 0.007(stat.) ± 0.038(norm.)) ± 10−4. We have also studied...
