Meson production on complex nuclei by pi^-- with the Crystal Ball detector
We report on preliminary results for the production of neutral mesons by 750 MeV/c pi^- on complex nuclear targets (C, Al, Cu) and hydrogen. Our simultaneous measurement of pi^0, eta and 2 pi^0 final states allows an investigation of the nuclear final state interaction effects. The data show thatbnuclear absorption is mainly responsible for an observed change in the shape of the 2 pi^0 invariant mass spectra. Our preliminary results for the sigma → gamma gamma ranching ratio is BR (sigma → gamma gamma) ≤ 3.6 x 10^-3 x Fi at 90% C.L. on a carbon target, where Fi is the fraction of 2 pi^0 produced via the σ intermediate state.
