Book Description
A new state with invariant mass near 2.32 GeV=c[sup 2] has been observed by the BABAR Collaboration in the inclusive D[sub s][sup +] [pi][sup 0] mass distribution using 91 fb[sup -1] of e[sup +]e[sup -] annihilation data taken at the PEP-II asymmetric-energy storage ring at energies near 10.6 GeV. The new state is narrow, with an observed width that is consistent with the experimental resolution. This narrow width combined with the quantum numbers of the final state imply that the decay is isospin-violating. The state has natural spin-parity, and its low mass suggests a J[sup P] = 0[sup +] assignment.

Book Description
The BABAR collaboration has observed a state of mass 2317 MeV/c[sup 2] which decays to D[sub s][pi][sup 0], using 91 fb[sup -1] of data from asymmetric e[sup +]e[sup -] collisions of energy around 10.6 GeV produced by the PEP-II storage ring. The observed width is compatible with the experimental resolution, indicating that the state is narrow, with [Gamma]

Book Description
A new state with invariant mass near 2.32 GeV=c2 has been observed by the BABAR Collaboration in the inclusive D{sub s} [pi]° mass distribution using 91 fb−1 of ee− annihilation data taken at the PEP-II asymmetric-energy storage ring at energies near 10.6 GeV. The new state is narrow, with an observed width that is consistent with the experimental resolution. This narrow width combined with the quantum numbers of the final state imply that the decay is isospin-violating. The state has natural spin-parity, and its low mass suggests a J{sup P} = 0+ assignment.
