Four-body Semileptonic Charm Decays $D\to P_1{P}_2{\ell }^{+}{\nu }_{\ell }$ Based on SU(3) Flavor Analysis

Ru-Min Wang, Yi Qiao, Yi-Jie Zhang +2

Motivated by the significant experimental progress in probing semileptonic decays $D\to P_1{P}_2{\ell }^{+}{\nu }_{\ell }(\ell =\mu ,e)$, we analyze the branching ratios of the $D\to P_1P_2\ell^+ν_\…
