The 0++ States
The data show five isoscalar resonances: f0(600), f0(980), f0(1370), f0(1500), and f0(1710). Of these the f0(600) is usually identified with the σ of chiral models. The decays and production of f0(1710) give strong evidence that it is also a meson.

Famous quotes containing the word states:
“Maybe we were the blind mechanics of disaster, but you don’t pin the guilt on the scientists that easily. You might as well pin it on M motherhood.... Every man who ever worked on this thing told you what would happen. The scientists signed petition after petition, but nobody listened. There was a choice. It was build the bombs and use them, or risk that the United States and the Soviet Union and the rest of us would find some way to go on living.”
—John Paxton (1911–1985)
