Same bump, different channel: Higgs fakes from technicolor

Abstract

Resonant production of a light, narrow techni-rho, followed by the decay ${\rho }_T\to W+{\pi }_T(jj)$ has been proposed as an explanation of the Wjj excess observed by CDF. If the ${\pi }_T$ decays to $\tau +\nu /{\tau }^{+}{\tau }^{-}$ rather than to jets, subsequent leptonic $\tau$ decay leads to ${\ell }^{+}{\ell }^{-}\nu \nu \bar{\nu }\bar{\nu }$, a final state that will be picked up by standard model $W{W}^{(\ast )}\to {\ell }^{+}{\ell }^{-}$ + MET Higgs searches. We point out that, for the same range of technicolor parameters required to fit the CDF Wjj excess, the correlated ${\ell }^{+}{\ell }^{-}$ + MET technicolor signal can have strength comparable to that of an intermediate-mass standard model Higgs boson, and therefore could be visible at the Tevatron or LHC.
