The NA62 experiment at CERN reports new results from the study of the radiative kaon decay K+ → π0e+νγ (Ke3γ), using a data sample recorded in 2017 and 2018. Preliminary results with the most precise measurement of the Ke3γ branching ratio, and a T-asymmetry measurement in the Ke3γ decay, are presented.
