An explanation of one-loop induced h→μτ decay

We discuss a possibility to explain the excess of h→μτ at one-loop level. We introduce three generations of vector-like lepton doublet L′ and two singlet scalars S1,2 which are odd under Z2, while all the standard model fields are even under this discrete symmetry. We show that S1 can be a good dark...
