Abstract
As a joint effort between DAΦNE and the KLOE-2 collaboration, the goal of reaching a total of 5 fb^-1 integrated luminosity in the data-taking campaign has been achieved. The acquired large sample combined with the KLOE data set corresponds to more than 2.4 × 10^10 φ and 3 × 10^8 η mesons produced, which makes it the largest φ-meson sample ever collected in e+ e- collisions.This allows precision measurements within the hadron physics program at KLOE/KLOE-2. The update on several ongoing analyses presented includes a status report on γγ physics, preliminary results on the B-boson search, a study of the η → π0 γ γ decay, and a measurement of the cross section for the e+ e- → π+ π- π0 process.
