On nature of scalar and tensor mesons from the analysis of processes pi-pi-> pi-pi, K-Kbar, eta-eta

Yu. S. Surovtsev, R. Kaminski, D. Krupa +1

Analysis of the isoscalar S- and D-waves of processes pi-pi-> pi-pi, K-Kbar, eta-eta is carried out aimed at studying the status and QCD nature of scalar and tensor mesons below 2…
