N2 - We report a search for the rare Dalitz decays and using data from the CMD-3 detector at the VEPP-2000 collider. These decays probe the electromagnetic structure of vector mesons and test the Vector Dominance Model (VDM) in low-energy QCD. A blind analysis technique, combined with kinematic constraints and multivariate methods, suppresses dominant backgrounds from and following with photon conversions. Preliminary results for the 2013 (12 pb) and 2018 (21 pb) datasets yield background estimates of and events, respectively. This study demonstrates sensitivity to branching ratios at the level, establishing CMD-3 as a key instrument for precision tests of VDM predictions.
