The string theory debate

There is a considerable debate, especially in the United States, about
the achievements and/or failure of string theory. The one outcome
of this is that there is pressure on the string community to come up with ways in which theory can be verified or falsified. Of note in this regard is the paper entitled

`` Falsifying String Theory Through WW Scattering''

by Distler, Grinstein and Rothstein. What is of course very gratifying to me is that ref.[2] of this paper is our work on axiomatic constraints on the low energy constants of chiral perturbation theory obtained from analyticity, unitarity, crossing and positivity considerations of neutral pion scattering . One has to read the paper of DGR to figure out the connections.
