Black disk radius constrained by unitarity
We argue that if the elastic proton–proton cross section increases with energy, the Froissart-like high energy behaviour of the elastic amplitude (which corresponds to a ‘black disk’ of radius R(s)=clns−βln(lns)) is the only possibility to satisfy the unitarity equation at each value of the impac...
