Exclusive production of π+π− and π0π0 pairs in photon-photon and in ultrarelativistic heavy ion collisions
The γγ → ππ reactions are discussed. To describe those processes, we include dipion continuum, resonances, high-energy pion-pion rescatterings, ρ meson exchange and pQCD Brodsky-Lepage mechanisms. The cross section for the production of pion pairs in photon-photon collisions in peripheral heavy ion...
