The likelyhood of black holes in LHC

From what I gather, only more exotic, extra-dimensional theories predict that there will be microscopic black holes produced in the Large Hadron Collider. And I get that even if they are produced they are very unlikely to be stable and even then they would probably be safe (just to let you know I'm not one of those the scientists-will-kill-us-all-quick-shut-down-all-the-particle-accelerators guys) . But is there any kind of estimation about how likely it is that some sort of black holes would be produced as opposed to a scenario where there wouldn't be any black holes at all? Thanks.

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
