Re:The "landscape" and falsifiability (Score 4, Interesting)

My officemate pointed me to a paper the other day where the authors (Distler, Grinstein, and Rothstein) were saying it might be possible to falsify strig theory with WW and ZZ scattering measurements (although they don't talk specifically about these measurements at LHC). The paper is on lanl.gov and the reference is hep-ph/0604255. I'm not a theorist, but it looks to me like the basic argument is that if there is no light higgs, and certain bounds on the WW and ZZ cross-sections are not satisfied, then the S-matrix is either non-analytic, non-unitary, or not Lorentz invariant at some scale. And the authors say that since string theory is constructed to satisfy these assumptions at all scales, it would be invalidated if one of them were not correct.

But I do find it rather amusing that you'd have to give up something like Lorentz invariance or unitarity to disprove string theory.
