Abstract

© 2020 authors. Published by the American Physical Society.Using 2.93 fb-1 of e+e- annihilation data collected at a center-of-mass energy s=3.773 GeV with the BESIII detector operating at the BEPCII collider, we search for the semileptonic D0(+) decays into a b1(1235)-(0) axial-vector meson for the first time. No significant signal is observed for either charge combination. The upper limits on the product branching fractions are BD0→b1(1235)-e+νe·Bb1(1235)-→ωπ-<1.12×10-4 and BD+→b1(1235)0e+νe·Bb1(1235)0→ωπ0<1.75×10-4 at the 90% confidence level.
