Relativistic quark clustering in the γγ → π+π- and π0π0 reactions
Description
Cross sections for pion pair production by photon-photon collisions are estimated near the threshold using a relativistic quark clustering model. A realistic q/bar q/ wave function of the pion was determined by fitting the pion charge form factor up to q2 = 4 /approximately/ 6GeV2/c2, the weak decay constant and the pion charge radius. The composite structure of the pion provides a simple explanation for the energy dependence and magnitudes of pi+pi- and pi0pi0 pair productions. 18 refs., 3 figs., 1 tab
