Spectrum and decay properties of bottomonium mesons.

We calculate the spectrum and wave functions (WFs) of various states of bottomonium( b b ¯ ) mesons using a non-relativistic quark potential model (NRQPM). The calculated WFs are used to compute the radiative widths of various states of b b ¯ . The strong decays widths of bottomonium states are also calculated using 3 P 0 model by choosing simple harmonic oscillator wave functions (SHOWFs). The β of SHOWFs for various states of the mesons are measured by fitting the numerical wave functions. The radiative and strong decay widths are used to calculate the branching ratios of b b ¯ mesons. We also compare our calculated masses and widths with available experimental data. On basis of this comparison, it is suggested that Υ (10860) is the 5S state of b b ¯ mesons. [ABSTRACT FROM AUTHOR]
