The production of a possible narrow charmed baryonic resonance decaying into a D meson and a proton in deep inelastic scattering at HERA is investigated. The analysis is based on data taken with the H1 detector in the years 2004-2007, corresponding to an integrated luminosity of ∼ 348 pb −1 . No significant signal is found and an upper limit on the number of signal events is determined at 95% confidence level, taking into account only statistical errors.
