Analysis of Λb→pK- and pπ- decays in a flavor changing Z' mode

Abstract: In this paper, we calculate the branching ratios of Λb→pK- and pπ- decays in the avor changing Z' model. We nd that the branching ratios for these two decay modes are sensitive to the contributions of the Z' boson. For Λb→pK- decay, if the left-handed couplings are equal to the right-handed couplings, the branching ratio of this decay could match up to the currently experimental data for ξs=0.01 and -52°<φsL<132°, or ξs=0.004 and 0°<φsL<84°; if only the left-handed couplings are considered, it could match up to the experimental data for ξs=0.01 and -10°φsL<138°. And for Λb→pK- decay, if the left-handed and right-handed couplings are equal, the branching ratio of Λb→pK- decay may be consistent with the currently experimental data with ξd=0.05 and -135°φdL<43°, if only the left-handed couplings are considered, it may be consistent with ξd=0.05 and -114°φdL<8°.
