Abstract
The annihilation channel (p) over bar p --> KLKS pi(0) pi(0) was studi ed with the Crystal Barrel detector at LEAR. This final state with neg ative C-parity is dominated by the strange resonances K(892), K-1(127 0), K-0(1400) and K-0*(1430). In addition, a J(PC) = 1(+-) state is s een in the KK decay mode. This state could be the isoscalar, axialvec tor h(1)' seen here with a mass of m = (1440 +/- 60)MeV/c(2) and a wid th of Gamma=(170 +/- 80)MeV/c(2). (C) 1997 Published by Elsevier Scien ce B.V.
