英文摘要 | In the littlest Higgs model with T-parity new flavor-changing interactions between mirror fermions and the standard model (SM) fermions can induce various flavor-changing neutral-current decays for B-mesons, the Z-boson, and the Higgs boson. Since all these decays induced in the littlest Higgs with T-parity model are correlated, in this work we perform a collective study for these decays, namely, the Z-boson decay Z -> b(s)overbar, the Higgs-boson decay h -> b(s)overbar, and the B-meson decays B -> X(s)gamma, B(s)->mu(+)mu(-), and B -> X(s)mu(+)mu(-). We find that under the current experimental constraints from the B-decays, the branching ratios of both Z -> b(s)overbar and h -> b(s)overbar can still deviate from the SM predictions significantly. In the parameter space allowed by the B-decays, the branching ratio of Z -> b(s)overbar can be enhanced up to 10(-7) (about one order above the SM prediction) while h -> b(s)overbar can be much suppressed relative to the SM prediction (about one order below the SM prediction). |
