Slide 3 S.Olsen CUSeeMe 4/12/96 Strong k1(1270) signal: SU(3) says roughly equal k1(1400) <-- where is it? Look for K1(1400) -Fit k* pi mass spectrum (Fig 4f) to: WMD-inspired K1(1270) line shape + BW[K1(1400)] + BW["k*(1680)"] | | (Fig 7) M fixed at 1.4 M around 1.7 Width " " 0.173 Width " 0.3 (bkgnd underestimated/signal overestimated?) Nevt(1400) = 26.8 +/- 10 evnts or Nevt < 39 90% cl Fig 7 -MC acceptance = 0.118 +/- 0.006 *********************************************************** * Br(psi'-->k1(1400)+ k- + cc) < 2.4 x 10^{-4} 90% cl * *********************************************************** -less than 1/3rd the psi'--> k1(1270) k branching fraction -no PDG entry for J/psi
