Rare K-Decays and its Strong Constraints on the Multiscale Walking Technicolor Model

  • We calculate the one-loop Z0-penguin contributions to the rare K-decays,K+→π+νν,KL→π0νν and KL→μ+μ, from the unit-charged pesudo-Goldstone bosons π1 and π8 in the framework of the Multiscale Walking Technicolor Model. We find that: (a) the π1 and π8 can provide one to three orders enhancements to the branching ratios of the rare K-decays under study; (b) the assumed mass ranges of the unit-charged PGBs in the Multiscale Walking Technicolor Model are excluded by the rare K-decay data. According to this and other relavent studies, one finds that the Multiscale Walking Technicolor Model are conflict with the data and therefore excluded.

Abstract: We calculate the one-loop Z0-penguin contributions to the rare K-decays,K+→π+νν,KL→π0νν and KL→μ+μ, from the unit-charged pesudo-Goldstone bosons π1 and π8 in the framework of the Multiscale Walking Technicolor Model. We find that: (a) the π1 and π8 can provide one to three orders enhancements to the branching ratios of the rare K-decays under study; (b) the assumed mass ranges of the unit-charged PGBs in the Multiscale Walking Technicolor Model are excluded by the rare K-decay data. According to this and other relavent studies, one finds that the Multiscale Walking Technicolor Model are conflict with the data and therefore excluded.
