摘要
Precision studies at electron-positron colliders with centre-of-mass energies in the charm-tau region and below have strongly contributed to our understanding of lightmeson interactions at low energies. We focus on the processes involving two or three light mesons with invariant masses below nucleon-antinucleon threshold. A prominent role is given to the interactions of the nine lightest pseudoscalar mesons (pions, kaons, eta, and eta') and the two narrow neutral isoscalar vector mesons omega and f phi. Experimental methods used to produce the mesons are reviewed as well as theory tools to extract properties of the meson-meson interactions. Examples of recent results from the DA Phi NE, BEPCII, and VEPP-2000 colliders are presented. In the outlook we briefly discuss prospects for further studies at future super-charm-tau factories.
