Same bump, different channel: Higgs fakes from technicolor

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 $\tau +\nu \mathrm{/}{\tau }^{+}{\tau }^{-}$ 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 $W{W}^{(\ast )}\to {\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-}$ + MET Higgs searches. We point out that, for the same range of technicolor parameters required to fit the CDF Wjj excess, the correlated ${\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-}$ + 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.
