Abstract
We calculate the contributions to the rare B-decays, B → Xs,dνν̄, and Bs,d → l+l- from the unit-charged technipions. Within the considered parameter space we find that: (a) the enhancements to the branching ratios in question can be as large as three orders of magnitude; (b) the ALEPH data of B → Xsνν̄ lead to strong mass bounds on mp1 and mp8: mp8 ⩾ 620, 475 GeV for FQ = 40 GeV and mp1 = 100, 400 GeV, respectively; (c) the CDF data of Bs → μμ̄ lead to a relatively weak limit: mp8 ⩾ 320 GeV for FQ = 40 GeV and mp1 = 200 GeV.
