We present a study of the D(+)pi(-), D(0)pi(+), and D*(+)pi(-) systems in inclusive e(+)e(-)-> c (c) over bar interactions in a search for new excited D meson states. We use a data set, consisting of similar to 454 fb(-1), collected at center-of-mass energies near 10.58 GeV by the BABAR detector at the SLAC PEP-II asymmetric-energy collider. We observe, for the first time, candidates for the radial excitations of the D(0), D*(0), and D*(+), as well as the L = 2 excited states of the D(0) and D(+), where L is the orbital angular momentum of the quarks.

Abstract

We present a study of the D(+)pi(-), D(0)pi(+), and D*(+)pi(-) systems in inclusive e(+)e(-)-> c (c) over bar interactions in a search for new excited D meson states. We use a data set, consisting of similar to 454 fb(-1), collected at center-of-mass energies near 10.58 GeV by the BABAR detector at the SLAC PEP-II asymmetric-energy collider. We observe, for the first time, candidates for the radial excitations of the D(0), D*(0), and D*(+), as well as the L = 2 excited states of the D(0) and D(+), where L is the orbital angular momentum of the quarks.
