The analysis is performed with a double-tag method. We do not observe a significant D+ -> gamma e(+)nu(e) signal, and obtain an upper limit on the branching fraction of D+ -> gamma e(+)nu(e) decay with the energy of radiative photon larger than 10 MeV of 3.0 x 10(-5) at the 90% confidence level.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8501959166610.1103/PhysRevD.95.071102Q1Q1WOS:000400142000001
