Axial vector meson production

Recently available differential cross section and density matrix information on pi /sup -/p to B/sup -/p at 4 GeV/c are successfully described in terms of t channel exchanges and s channel absorptive effects. The s channel helicity amplitude which is dominant at small mod t mod (zero net helicity fl...

description Recently available differential cross section and density matrix information on pi /sup -/p to B/sup -/p at 4 GeV/c are successfully described in terms of t channel exchanges and s channel absorptive effects. The s channel helicity amplitude which is dominant at small mod t mod (zero net helicity flip omega exchange) is found to have a zero at -t=0.2 GeV/sup 2/. Su(3) and higher symmetries are used to predict cross sections for further axial vector meson production processes, in particular non-diffractive A/sub 1/ production. The importance of these processes with regard to Regge phenomenology and meson spectroscopy is emphasized. (24 refs).
