Two-pion emission decays of negative parity singly heavy baryons

Nongnapat Ponkhuha, Ahmad Jafar Arifi, Daris Samart

We investigate two-pion emission decays of singly charmed and bottom baryons, focusing on ${\Lambda }_Q^{\ast }(1P)$ and ${\Xi }_Q^{\ast }(1P)$ with $Q=c$ (charm) or $b$ (bottom) quarks and $J^P=1/2^-,3/2^-…
