Query: Constraints on lepton flavor violation in the two Higgs doublet model   Constraints on the whole spectrum of lepton flavor violating vertices are
shown in the context of the standard two Higgs doublet model. The vertex
involving the $e-\tau$ mixing is much more constrained than the others, and the
decays proportional to such vertex are usually very suppressed.
