Study of 𝐵 → X_𝑐 Λ⁰ Kₛ/𝐾 with recoil mass approach

This is the authors' abstract. We don't add key points for this paper.

In this study we search for decays B⁰→ Xc⁻ Λ⁰ K⁺ and B⁰→ X̄c⁰ Λ⁰ Kₛ⁰ using Belle simulation, where Xc represents a charm baryon. Belle collected data at a center of mass energy close to Υ(4S) resonance, which decays only to two B mesons almost every time. We follow a recoil approach where the other B meson is reconstructed in various hadronic modes, and the charm baryon is looked for in the recoil of the accompanying Λ⁰ and K/Kₛ coming from signal B. This study will provide a comprehensive insight into B→ baryonic decays and the impact of ss̄ quark pair production on the branching fractions.
