B-Physics at ATLAS and CMS

B-physics results from ATLAS and CMS experiments are reviewed. Those include: studies of J/ψ pair production at ATLAS and CMS: di-charmonium exotics, triple J/ψ production at CMS; pentaquark and tetraquark studies in B-hadron decays at ATLAS; differential cross-section measurements of J/ψ production at ATLAS and CMS; measurements of the CP-violating phase in Bs →J/ψϕ decays at ATLAS and CMS; combination of LHCb, ATLAS, CMS results for Bs→μμ, B0→μμ rare decays; summary of recent Bc-meson results; observation of B0→ψ(2S)Ks0π+π- and Bs→ψ(2S)Ks0 decays at CMS; angular analysis of B-meson decays at ATLAS and CMS; observation of Ξ-b(6100) excited bottom-strange baryon state in Ξ-bππ decay channel, etc.
