A search for Bₒ₀^* and B^*ₒ₁ through the K^-p interaction

Abstract Studying heavy-quark hadrons is crucial due to the nonperturbative nature of low-energy QCD, with Heavy-Quark Symmetry (HQS) serving as a key framework for understanding their spin and flavor symmetries. However, a key issue is that the theoretically expected B^ (*) K B (∗) K ¯ molecular states have not yet been observed, although they are considered the bottom-quark counterparts of the observed D^ (*) K D ¯ (∗) K ¯ molecular states (corresponding to Dₒ₀ (2317/2460) ^- D s 0 (2317 / 2460) -), which challenges the universality of HQS. The main goal of this work is to search for the theoretically predicted BK B K ¯ and B^*K B ∗ K ¯ molecular states, namely Bₒ₀^* (5725) B s 0 ∗ (5725) and Bₒ₁^* (5778) B s 1 ∗ (5778), via the reactions K^-p ₁^0 Bₒ₀^* K - p → Λ b
