Description
The Two Higgs Doublet Model invariant under the gauge group SU (2) × U (1) is known to have six
additional global discrete or continuous symmetries of its scalar sector. We have discovered regions
of parameter space of the model which are basis and renormalization group invariant to all orders
of perturbation theory in the scalar and gauge sectors, but correspond to none of the hitherto
considered symmetries. We therefore identify seven new symmetries of the model and discuss their
phenomenology.
