Longer lived mini black holes

Production of tidal-charged black holes at the Large Hadron Collider

I see from the above paper that physicists are still looking at certain theorised types of black holes that the LHC might produce, and which might "live" long enough to leave the detector. (I presume instead of instantaneously turning into a spray of decay particles.)

This guy reckons that they are unlikely to be produced in the lifetime of the LHC. (I see that he mentions Plaga's paper - predicting one possible form of black hole disaster - in his footnotes too, even though he makes no comment on it.)

I should be encouraged by the result, but I am still struck by how little they know about what may really happen there.
