Lightest scalar and tensor resonances in $γ γ \to π π$ after the Belle experiment

N. N. Achasov, G. N. Shestakov

New high statistics Belle data on the $γ γ \to π^{+} π^{-}$ reaction cross section measured in the range of pion-pair invariant masses $s$ between 0.8 GeV and 1.5 GeV are analyzed t…

Lightest scalar in the SU_L(2)*SU_R(2) linear σmodel

N. N. Achasov, G. N. Shestakov

We consider the lightest scalar meson in the frame of the $S U_{L} (2) \times S U_{R} (2)$ linear $σ$ model, keeping in mind that this model could be the low energy realization of the two-f…
