Abstract

We study three-body decays of Λc∗(2765)→Λc+π+π−\Lambda_c^{*}(2765) \to \Lambda_c^+\pi^+\pi^- by using effective Lagrangians in a non-relativistic framework. We consider the sequential decays through Σc(2455)π\Sigma_c(2455)\pi and Σc∗(2520)π\Sigma_c^*(2520)\pi in intermediate states which are dominant contributions. The coupling constants in the effective Lagrangians are computed in the quark model. We demonstrate that the ratio R=Γ(Λc∗→Σc∗(2520)π)/Γ(Λc∗→Σc(2455)π)R= \Gamma(\Lambda_c^*\to\Sigma_c^*(2520)\pi)/\Gamma(\Lambda_c^*\to \Sigma_c(2455)\pi) and angular correlations are sensitive to the spin and parity of Λc∗(2765)\Lambda_c^{*}(2765). Thus, the measurement of these observables in experimental facilities such as Belle and LHCb can provide useful constraints to determine the spin and parity of Λc∗(2765)\Lambda_c^{*}(2765).
