Study of the process (pi)(sup -)A(yields)(pi)(sup -)(eta)'(eta)A at the moment 36 GeV/c
Abstract
Reaction pi(-)A yields pi (-)(eta)'(eta)A has been studied at 36 GeV/c beam momentum. The new state near the threshold of pi(-)(eta)'(eta) decaying through the pi(-)f(sub0)(1590) has been observed. The combined analysis of two channels pi(-)(eta)'(eta) and pi(-)(eta)'(eta) gives for branching ratio: Br(X yields pi(-)(eta)'(eta)) /Br(X yields pi(-)(eta)(eta)) = 029 +/- 0.07.
