Lepton flavor violation within the Simplest Little Higgs model

Abstract

We carry out an exhaustive analysis of lepton flavor violating processes within the Simplest Little Higgs model. Its discovery could be expected from either $\mu \to e$ conversion in nuclei, $\mu \to e\gamma$ or $\mu \to 3e$ decays. Then, the tau sector could help discriminating this model not only via $\tau \to \ell \gamma$ ($\ell =\mu ,e$) and $\tau \to 3\ell$ decays, but also by means of $\ell \to \tau$ conversion in nuclei, which is promising in this respect. Although the model violates slightly custodial symmetry, acommodating the recent CDF $M_W$ measurement is in tension with electroweak precision data.
