In this paper, we explore the decay {eta}{sub b}{yields}{tau}{sup +}{tau}{sup -} as a probe for a light pseudoscalar or a light axial vector state. We estimate the standard model branching ratio for this decay to be {approx}4x10{sup -9}. We show that considerably larger branching ratios, up to the present experimental limit of {approx}8%, are possible in models with a light pseudoscalar or a light axial vector state. As we do not include possible mixing effects between the light pseudoscalar and the {eta}{sub b}, our results should be reliable when the pseudoscalar mass is away from the {eta}{sub b} mass.
