Abstract
AbstractAn analytical study of a source of Beauty mesons (B mesons) by the Strong decay of $$\Upsilon$$
Υ
(11020) is performed to obtain various modes of B mesons. The non-relativistic quark model framework is used to predict the masses of the bottomonium mesons. The strong decay of the $$\Upsilon$$
Υ
(11020) state is calculated utilizing Quark Pair Creation model. In addition, the branching ratio of the strong decay has been calculated for each decay width and using them to estimate the number of B-meson pairs for each strong decay width. The results show reasonable agreement with recent Particle Data Group data, in particular with the total strong decay width of $$\Upsilon$$
Υ
(11020). The $$\Upsilon$$
Υ
(11020) particle is expected to be a good candidate for the conventional $$\Upsilon$$
Υ
(6S) state and provides both types of strange and non-strange B mesons. We found new conclusions for the strong decay widths of the $$\Upsilon$$
Υ
(11020) in the relativistic phase space. The strong width of the $$B^{*}B^{*}$$
