Phenomenological upper and lower bounds on the $\pi\pi S$ wave scattering lengths
Starting from a given phenomenological input (upper and lower bounds of the real and imaginary parts of the pi /sup 0/ pi /sup 0/ and pi /sup +/ pi /sup 0/ amplitudes in the region 0.45 GeV<or=E/sub cm/<or =1.9 GeV; 0<or=t<or=4 mu /sup 2/) rigorous upper and lower bounds are derived on t...
