HQET Spectroscopy of Radially Excited F-wave Mesons

Abstract

Motivated by the continuous advances in modern experimental facilities, we investigate the radially excited F-wave bottom and bottom-strange mesons that have not yet been observed experimentally. By combining theoretical inputs with available experimental information on charm mesons and applying flavor-symmetry parameters, we predict the masses of the radially excited F-wave bottom states and their strange partners. In addition, we compute their strong decay widths in terms of the hadronic coupling constants ${\tilde{g}}_{ZH}$ and ${\tilde{g}}_{RH}$. Using the presently estimated values of these couplings, we obtain upper bounds on the corresponding decay widths. These predictions will serve as testable benchmarks for forthcoming heavy-flavor spectroscopy findings.
