Measurement of radiative processes at NA48

The first part of this paper will review the new results in the radiative decays of charged kaons available from the NA48/2 experiment at CERN: the first measurement of the DE and INT contribution to the decay $K^{\pm} \rightarrow \pi^{\pm}\pi^{0}\gamma$ in the $T_{\pi}^{*}$ region $0 < T_{\pi}^{*}$ 80 MeV and the first observation of $K^{\pm} \rightarrow \pi^{\pm}e^{+}e^{−}\gamma$ decay. Then in the second part of the paper new results on radiative hyperon decays, concerning the measurement of $\Xi^{0} \rightarrow \Lambda\gamma$ decay asymmetry and the first observation of the $\Xi^{0} \rightarrow \Lambda e^{+}e^{−}$ decay from NA48/I, will be reported.
