Abstract

LHCb has productive studies of quarkonia and b-hadrons which provide essential inputs to study quantum chromodynamics (QCD). In this proceeding, seven recent results are reported: the observation of a new excited Ξ_b⁰ resonance in Ξ_b^- π⁺ final states, the new excited B_s⁰ state is observed in B⁺ K^- mass spectrum, the first observation of suppressed semileptonic B_s⁰ → K^- μ⁺ ν_μ decay, the first observation of the decay B⁰ → D⁰ D⁰ K⁺ π^-, the first observation of the Cabibbo-suppressed decay Λ_b⁰ → χ_c1 p π^-, the first observation of Λ_b⁰ → Λ_c⁺ K⁺ K^- π^- decay, and end this report with the first search for the doubly heavy baryon Ω_bc⁰ and a search for Ξ_bc⁰ baryon.
