The results continue to pour out of the LHC’s first production run. This week, the folks behind the CMS detector have announced the submission of a paper to Physics Letters that describes a test of some forms of string theory. If this form of the theory were right, the LHC should have been able to produce small black holes that would instantly decay (and not, as some had feared, devour the Earth). But a look at the data obtained by CMS shows that a signature of the black holes’ decay is notably absent. […]
Contrary to some reports, this result doesn’t mean the death of string theory, only the particular flavor that predicted black holes at these energies. Eliminating some models is a critical process of narrowing down what’s possible, but most theoretical constructs have a range of possible models, and string theory is no different. In fact, it’s entirely possible that the ADD model was generated simply because physicists were looking for something they could possibly test in the LHC.
