Rare Decays B→ Xs,d vv and Bs,d →1+1- in the Multiscale Walking Technicolor Model
-
Abstract
We calculate the contributions to the rare B-decays, B→Xs,d vv 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→ Xsvv lead to strong mass bounds on mpl and mp8: mp8 ≥ 620,475 GeV for FQ = 40 GeV and mpl = 100,400 GeV, respectively; (c) the CDF data of Bs→μμ lead to a relatively weak limit: mp8 ≥ 320 GeV for FQ = 40 GeV and mpl = 200 GeV.
