5 A complicatiion…  Unitarity!
RENORM predictions for  diffraction at LHC confirmed Theoretical Complication: Unitarity! A complicatiion…  Unitarity! ssd grows faster than st as s increases *  unitarity violation at high s (also true for partial x-sections in impact parameter space) the unitarity limit is already reached at √s ~ 2 TeV need unitarization * similarly for (dsel/dt)t=0 w.r.t. st, but this is handled differently in RENORM Moriond QCD 2016 RENORM Tensor-Pomeron Diffractive Predictions K.
