Abstract A search for processes producing large missing transverse momentum in conjunction with an energetic, isolated photon in ep collisions is reported. The data were collected at the H1 detector at HERA in the years 1994 to 2000, at centre-of-mass energy of 300 and 320 GeV. The data are presented, within the context of the Standard Model, as the first measurement of radiative charged current interactions. Limits are derived upon anomalous coupling of the W-W-gamma vertex. The data are also discussed in terms of possible physics beyond the Standard Model.
