Query: $H\to \ell\ell'$ in the Simplest Little Higgs Model   Little Higgs Models are promising constructs to solve the hierarchy problem
affecting the Higgs boson mass for generic new physics. However, their
preservation of lepton universality forbids them to account for the
$H\to\tau\mu$ CMS hint and at the same time respect (as they do) the severe
limits on $H\to\mu e$ inherited from the non-observation of $\mu\to e\gamma$.
We compute the predictions of the Simplest Little Higgs Model for the $H\to
\ell\ell'$ decays and conclude that the measurement of any of these decays at
LHC (even with a much smaller rate than currently hinted) would, under
reasonable assumptions, disfavor this model. This result is consistent with our
earlier observation of very suppressed lepton flavor violating semileptonic tau
decays within this model.
