Testing the light scalar meson as a non- q q ¯ $$ q\overline{q} $$ state in semileptonic D decays
Abstract While the light scalar mesons (S 0) are considered to be either ordinary q q ¯ $$ q\overline{q} $$ or exotic tetraquark states, we investigate the semileptonic decays D → S 0 e + ν e , by taking into account the resonant effects of S 0 → M 1 M 2, where S 0 = a 0(980), f 0(980), and f 0(500)...
