TL;DR
This paper reports the observation of the f0(1770) resonance decaying into eta-eta in antiproton-proton reactions at various beam momenta, providing measurements of its mass and width.
Contribution
First observation of the f0(1770) -> eta-eta decay in pbar-p reactions with detailed mass and width measurements.
Findings
Clear signal of f0(1770) at higher beam momenta
Mass of 1770±12 MeV for the resonance
Width of 220±40 MeV for the resonance
Abstract
We present data on pbar-p -> eta-eta-pizero at beam momenta of 600, 900, 1050, and 1200 MeV/c. At the higher three momenta, a signal is clearly visible due to pbar-p -> f_0(1770)-pizero, f_0(1770) -> eta-eta. It has mass 1770+-12 MeV and width 220+-40 MeV, where errors cover systematic uncertainties as well as statistics.
