Journal of High Energy Physics. ISSN 1029-8479. N.º 11 (2018), pp. 1-221029-8479http://hdl.handle.net/10400.21/9096We build a model containing two scalar doublets and a scalar singlet with a specific discrete symmetry. After spontaneous symmetry breaking, the model has Standard Model-like phenomenology, as well as a hidden scalar sector which provides a viable dark matter candidate. We show that CP violation in the scalar sector occurs exclusively in the hidden sector, and consider possible experimental signatures of this CP violation. In particular, we study contribution to anomalous gauge couplings from the hidden scalars.engBeyond standard modelHiggs physicsjournal article10.1007/JHEP11(2018)091
