In this paper we calculated the partial next-to-leading order (NLO) contributions to $B_s \\to K\\pi$ decays by employing the pQCD approach, we found numerically that (a) for $B_s \\to K^+ \\pi^-$ decay the consistency between the pQCD prediction and the measured value is improved effectively by the inclusion of the NLO contributions; (b) for $B_s \\to K^0\\pi^0$ decay, the NLO enhancement to the branching ratios can be significant, $\\sim 60\\%$, to be tested by the LHC experiment.
Keywords:$B_s$ meson decay;the pQCD factorization approach;Branching ratio
