Role of the hadron molecule Λc (2940) in the p(p)over-bar → pD0(Λ)over-barc (2286) annihilation reaction

The annihilation process p (p) over bar -> pD(0)(Lambda) over bar (c)(2286) is studied taking into account t-channel D-0, D*(0) meson exchange and the resonance contribution of Lambda(c)(2286) and Lambda(c)(2940) baryons. We assume that the Lambda(c)(2940) baryon is a pD*(0) molecular state with spin-parity 1/2(+) and 1/2(-). Our results show that near the threshold of p (p) over bar -> Lambda(c)(2286)(Lambda) over bar (c)(2286) the contribution from the intermediate state Lambda(c)(2940) is also sizeable and can be observed at the (P) over bar ANDA experiment. Another conclusion is that the spin-parity assignment 1/2(-) for Lambda(c)(2940) gives enhancement for the cross section in comparison with a choice 1/2(+).
