Newly Observed \(B_{sJ}(6063)\) and  \(B_{sJ}(6114)\) Mesons in HQET

Motivated by the recent discoveries of the orbital excitations \(B_{sJ}(6063)\) and \(B_{sJ}(6114)\) by the LHCb Collaboration [Eur. Phys. J. C 81.7 (2021), p. 601] we conducted a comprehensive investigation of the excited \(B_s\) mesons within the framework of the heavy quark effective theory (HQET). By leveraging the spin-flavor symmetry of the heavy quark and the chiral symmetry of the light quark, we explore the flavor-independent parameters \(\Delta _F^{(c)} = \Delta _F^{(b)}\) and \(\lambda _F^{(c)} = \lambda _F^{(b)}\) to compute the masses of bottom mesons that have not yet been experimentally identified. Furthermore, I determine their strong decay behavior into ground state bottom mesons along with light pseudoscalar mesons. This study not only contributes to our understanding of the properties of these observed bottom mesons but also provides valuable insights for future experimental investigations into radially and orbitally excited states.
