Two-body charmed baryon decays involving vector meson with $SU(3)$ flavor symmetry

We study the two-body anti-triplet charmed baryon decays of ${\bf B}_c\to {\bf B}_n V$,with${\bf B}_c=(\Xi_c^{0},-\Xi_c^{+},\Lambda_c^+)$and${\bf B}n(V)$thebaryon(vectormeson)states\mathrm{.}Basedonthe$SU(3)$ flavor symmetry, we predict that ${\cal B}(\Lambda^{+}{c}\to \Sigma^{+}\rho^{0},\Lambda^0 \rho^+)=(0.61\pm 0.46,0.74\pm 0.34)%$, in agreement with the experimental upper bounds of $(1.7,6)\mathrm{\%}$, respectively. We also find ${\cal B}(\Lambda^+_c \to \Xi^0 K^{+},\Sigma^0 K^{+},\Lambda^0 K^{*+}) =(8.7 \pm 2.7,1.2\pm 0.3,2.0\pm 0.5)\times 10^{-3}$ to be compatible with the pseudoscalar counterparts. For the doubly Cabibbo-suppressed decay ${\mathrm{\Xi }}_c^{+}\to p\varphi$, measured for the first time, we predict its branching ratio to be $(1.5\pm 0.7)\times {10}^{-4}$, together with ${\cal B}(\Xi^+_c \to p \bar K^{*0},\Sigma^+ \phi) =(7.8 \pm 2.2,1.9\pm0.9)\times 10^{-3}$\mathrm{.}The${\bf B}_c\to{\bf B}_n V$decayswith${\cal B}\simeq {\cal O}(10^{-4}-10^{-3})$ are accessible to the BESIII, BELLEII and LHCb experiments.
