A detailed analysis is conducted on the sources of Beauty mesons (B mesons) through the strong decay of ηb(5S), which represents one of the singlet-spin states S-wave bottomonium mesons. That is considered a significant step in understanding the physics behind the strong decay of bottomonium mesons, which is demonstrated to furnish us with a plentiful source of Beauty mesons. Their rare decay is regarded as a gateway to a new realm of physics, commonly called New Physics or Beyond Standard Model. The expected masses for higher bottomonium mesons are determined within the framework of the nonrelativistic quark model, and the recently obtained experimental data exhibit substantial concordance with our findings. Additionally, other theoretical forecasts align with our outcomes. The Quark Pair Creation model is employed to compute the strong decay of the ηb(5S) meson. Moreover, the strong decay branching ratio is determined. Novel findings regarding the partial strong decay widths of the ηb(5S) are obtained, while the total decay width aligns with previous studies. The strong decay width of the B*B* mesonic pairs channel is expected to be the greatest width by the ratio (∼ 56.37 %) concerning the higher scalar ηb(5S) state. Additionally, the Bs*Bs* channel is predicted to have the next-to-dominant width relative to ηb(5S) state.
