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

We study the two-body anti-triplet charmed baryon decays of B-c -> BnV, with B-c = (Xi(0)(c), -Xi(+)(c), Lambda(+)(c)) and B-n(V) the baryon (vector meson) states. Based on the SU(3) flavor symmetry, we predict that B(Lambda(+)(c) -> Sigma(+) rho(0), Lambda(0) rho(+)) = (0.61 +/- 0.46, 0.74 +/- 0.34)%, in agreement with the experimental upper bounds of (1.7, 6)%, respectively. We also find B(Lambda(+)(c) -> Xi K-0*(+), Sigma K-0*(+), Lambda K-0*(+)) = (8.7 +/- 2.7, 1.2 +/- 0.3, 2.0 +/- 0.5) x 10(-3) to be compatible with the pseudoscalar counterparts. For the doubly Cabibbo-suppressed decay Xi(+)(c) -> p phi, measured for the first time, we predict its branching ratio to be (1.5 +/- 0.7) x 10(-4), together with B(Xi(+)(c) -> p (K) over bar*(0), Sigma(+)phi) = (7.8 +/- 2.2, 1.9 +/- 0.9) x 10 (-3). The B-c -> BnV decays with B similar or equal to O(10(-4) - 10(-3)) are accessible to the BESIII, BELLEII and LHCb experiments. (C) 2019 Published by Elsevier B.V.
