Comments on high-energy total cross sections in QCD
We discuss how hadronic total cross sections at high energy depend on the details of QCD, namely on the number of colours Nc and the quark masses. We find that while a “Froissart”-type behaviour σtot∼Blog2s is rather general, relying only on the presence of higher-spin stable particles in the spect...
