Cabibbo-favored ${\Lambda }_c^{+}\to \Lambda a_0(980{)}^{+}$ decay in the final state interaction

Yao Yu, Yu-Kuo Hsiao

The anti-triplet charmed baryon decays with the light scalar mesons are rarely measured, whereas the recent observation of the Cabibbo-favored ${\Lambda }_c^{+}\to \Lambda \eta {\pi }^{+}$ decay hints a possib…
