Bootstrapping mesons at large NN: Regge trajectory from spin-two maximization

By Jan Albert and others
We continue the investigation of large NN QCD from a modern bootstrap perspective, focusing on the mesons. We make the natural spectral assumption that the 222 \to 2 pion amplitude must contain, above the spin-one rho meson, a massive resonance of spin two. By maximizing its coupling we find a...
