We discuss the e+e−→(hA)→bbbb cross section in an Abelian
extended SM. We work in that minimum of the scalar potential for which Higgs
trilier coupling is greater than the soft mass parameters. We find that
nex-to-lightest Higgs gives the essential contribution to the cross section in
the small Z−Z′ mixing angle and leptophobic Z′ limit.Comment: 13 pages, 1 postscript figur
