Placing of the recently observed bottom strange states B_sJ(6063) and B_sJ(6114) in bottom spectra

We employ the heavy quark effective theory (HQET) to give spin-parity quantum numbers for the bottom strange states B_sJ(6063) and B_sJ(6114) recently observed by the LHCb Collaboration [9]. By exploring flavor-independent parameters ${\Delta }_F^{\left(c\right)}={\Delta }_F^{\left(b\right)}$ and ${\lambda }_F^{\left(c\right)}={\lambda }_F^{\left(b\right)}$ appearing in the HQET Lagrangian, we calculate the masses of the experimentally missing bottom strange meson states 2S, 1P, 1D. The parameter Δ_F appears in the HQET Lagrangian and gives the spin-averaged mass splitting between excited-state doublets (F) and ground-state doublets (H). Another parameter λ_F comes from first-order corrections in the HQET Lagrangian and gives hyperfine splittings. We also analyze these bottom strange masses by taking 1/m_Q corrections, which lead to modifications of parameter terms of ${\Delta }_F^{\left(b\right)}={\Delta }_F^{\left(c\right)}+\delta {\Delta }_F$ and ${\lambda }_F^{\left(b\right)}={\lambda }_F^{\left(c\right)}\delta {\lambda }_F$. Further, we analyze their two-body decays, couplings, and branching ratios via the emission of light pseudoscalar mesons. Based on the predicted masses and decay widths, we tentatively identify the states B_sJ(6063) as 2³S₁ and B_sJ(6114) as 1³D₁. Our predictions provide crucial information for future experimental studies.
