In principle the vacuum ought to be determined by cosmic initial conditions and/or anthropic selection, but that's just too hard for now. So the only way LHC observations could actually disfavor string theory - as opposed to simply moving the target for string phenomenology - would be if they provided evidence that the field theory of the real world is in Vafa's "swampland" of field theories not in the string landscape. | |

In his post about the implications of the higgs search up to now profmattstrassler.com/articles-and-posts/the-higgs-particle/… Matt Strassler says that if no higgs is seen it would be not so unlikely that hints of a technicolor scenario could kick in whe LHC runs at 14 TeV. Would technicolor change the picture ? I admit that I know not more about it than Matt Strassler writes ;-/ ... | |
