title = "Observation of the D, E and δ mesons in π-p interactions at 12 and 15 GeV/c",
abstract = "We have observed the D(1285), E(1420) and δ(975) mesons produced in 12 and 15 GeV/c π-p interactions at the CERN Omega Spectrometer. Production cross sections and decay branching ratios are presented. Analysis of the decay D(1285) → δ(975) π favours a spin-parity assignment of 1+.",

note = "Funding Information: the experiment. We gratefully acknowledge the continuing generous support of the Science Research Council. Especial thanks are due to D. Eastwood for his conscientious help in processing the data. Funding Information: The axial vector mesons represent a tantalising area of uncertainty in the application of the constituent quark model to conventional hadronic spectroscopy. Several negative G-parity states are missing, and of the positive G-parity states only the B(1235) is completely established. Among the candidates for the latter states, the * Now at Philco-Ford, Philadelphia, USA. ** Now at the University of Birmingham, UK. *** Supported by the Israel Academy of Science and Humanities, The Israel Commission for Basic Research, Israel. + Now at Rutherford Laboratory, UK. ++ Now at Carnegie-Mellon University, USA. +++ Now at CERN, Geneva, Switzerland.",
