Study of 1F doublet (3⁺, 4⁺) for bottom spectra using HQET

Mesons carrying one heavy quark (Q=c,b) and one light quark (q=u,d,s) act as the hydrogen atom of hadron physics and provides a good platform to study non-perturbative QCD. In the last decade, meson spectroscopy has undergone the discovery of many new mesons like D*₂(3000), B_J(5970), B_J(5840) etc. These newly observed higher excited charm and bottom states observed by LHCb, CDF, D0, CLEO, BaBar collaborations stimulates the interest of theorists to check the authenticity of the theoretically available models for these upcoming data. It also motivates the theorists to fill the void in the spectrum. So in the same context, we use heavy quark effective theory (HQET) to explore the heavy quark flavor symmetry property to predict the masses and strong decay properties of experimentally missing 1F_7/2 bottom states B₃, B₄*, B_S3 and B_s*₄. The comparison of our result with other theoretically available data also help in checking the validity of this symmetry for higher excited states
