1  OAKDEN 1994 makes an amplitude analysis of LEAR data on ${{\overline{\mathit p}}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit \pi}}{{\mathit \pi}}$ using a method based on Barrelet zeros. This is solution A. The amplitude analysis of HASAN 1994 includes earlier data as well, and assume that the data can be parametrized in terms of towers of nearly degenerate resonances on the leading Regge trajectory. See also KLOET 1996 and MARTIN 1997 who make related analyses.
