The authors' main claim In this letter, we show that the parameter range which was considered by the CMS collaboration is actually out of the validity range of semi-classical black hole picture so that the Monte-Carlo simulation result which was crucially used in the analysis still needs further solid scientific basis.

Recently the CMS collaboration at the LHC reported "the first direct limit on black hole production at a particle accelerator" using a data sample corresponding to an integrated luminosity of 35/pb of pp-collision at a center of mass energy of 7 TeV. Even though the result has a strong impact on future searches, the interpretation lacks enough theoretical support. In this letter, we show that the parameter range which was considered by the CMS collaboration is actually out of the validity range of semi-classical black hole picture so that the Monte-Carlo simulation result which was crucially used in the analysis still needs further solid scientific basis.

We critically re-examined the recent microscopic black hole search by the CMS collaboration at the LHC [ref] and found that the claimed excluded range of microscopic black hole mass is not justified by currently available theoretical studies unfortunately.

Indeed low energy gravity scenarios based on large or warped extra dimension(s) [ref] predict that a high energy collider, such as the LHC, may have a chance to produce a sizable number of microscopic black holes [ref] if the collision energy would be exceedingly larger than the scale where higher dimensional gravity becomes strong [ref] .
