Rare decays of beauty particles were studied in several two-body exclusive hadronic charmless modes using the 19.4 pb^-1 Z-pole data collected with the SLD detector at SLAC from 1993 to 1998. These decays are mediated by both tree level b [yields] u and one-loop penguin b [yields] s, d transitions. Upper limits for the branching ratios are set for the investigated modes B_s, B₀ [yields] P⁺P^-, B⁺ [yields] V P⁺ and B_s, B⁰ [yields] V V , where the pseudoscalar particle P⁺ is either [pi]⁺ or K⁺ and the vector particle V is either [rho]⁰, K^{* 0} or [phi]. Using an event selection algorithm consisting of a set of hard cuts combined with a set of discriminator functions, the efficiencies range between 24% and 37% with near zero background.
