Search for the lepton-flavor-violating decays $B^{\pm} \to h^{\pm} \tau \ell$ $(h=K,\pi;\ell=e,\mu)$ at {\sc BaBar}

We present a search for the lepton-flavor-violating decays $B^{\pm} \to h^{\pm} \tau \ell$ ($h= K,\pi$; $\ell= e,\mu$) using the full {\sc BaBar} dataset, which corresponds to 471.9 million $B\bar{B}$ pairs. The search uses a sample of events where one $B$ meson (the ``tag'' $B$) is fully reconstructed in one of several hadronic final states. Using the tag-$B$ momentum and the reconstructed $h$ and $\ell$, we are able to fully reconstruct the $\tau$ 4-momentum. The reconstructed $\tau$ mass is our main discriminant against combinatoric background.
