Using the Gaussian wave function mass spectra and decay rates of bb̄ meson are investigated in the framework of phenomenological quark anti-quark potential (coulomb plus power) model consisting of relativistic corrections to the kinetic energy term. The spin-spin, spin-orbit and tensor interactions are employed to obtain the pseudoscalar and vector meson masses. The decay constants (fP/V) are computed using the wave function at the origin. The di-gamma and di-leptonic decays of the bb̄ meson are investigated using Van-Rayan Weisskopf formula as well as in the NRQCD formalism.
