Rare B-Decays and Z0-Penguin Contributions From the Charged Pseudo-Goldstone Bosons

  • In this paper, the one-loop contributions to the rare B-decays B→Xs,dνν and Bs,d→1+1(1= e,μ,τ) from the charged pesudo-Goldstone bosons P± and P±8 are calculated. Within the parameter space, we find that: (a) the P± and P8± can provide rather large enhancements to the branching ratios of the rare B-decays in question, the maximum increase is about a factor of 3 to Br(B→Xs,d,νν), and a factor of 5 to Br (Bs,d→1+1); (b) the color-octet pesudo-Goldstone boson P±8 dominates the contributions to all rare B-decays under consideration; (c) no limit on the masses of charged pesudo-Goldstone bosons can be achieved from the current experimental data, but the forthcoming data may reach the sensitivity to find the signals of new physics beyond the Standard Model.

Within the parameter space, we find that: (a) the P± and P8± can provide rather large enhancements to the branching ratios of the rare B-decays in question, the maximum increase is about a factor of 3 to Br(B→Xs,d,νν), and a factor of 5 to Br (Bs,d→1+1); (b) the color-octet pesudo-Goldstone boson P±8 dominates the contributions to all rare B-decays under consideration; (c) no limit on the masses of charged pesudo-Goldstone bosons can be achieved from the current experimental data, but the forthcoming data may reach the sensitivity to find the signals of new physics beyond the Standard Model.
