N2 - By analyzing a 2.93 fb-1 data sample of e+e- collisions, recorded at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report the first observation of the semileptonic D+ transition into the axial-vector meson D+→K̄1(1270)0e+νe with a statistical significance greater than 10σ. Its decay branching fraction is determined to be B[D+→K̄1(1270)0e+νe]=(2.30±0.26-0.21+0.18±0.25)×10-3, where the first and second uncertainties are statistical and systematic, respectively, and the third originates from the input branching fraction of K̄1(1270)0→K-π+π0.
