Alignment limit in three Higgs-doublet models
abstract
The LHC Higgs data is showing a gradual inclination towards the SM result and realization of an SM-like limit becomes essential for BSM scenarios to survive. Considering the accuracy that can be achieved in future colliders, BSMs that acquire the alignment limit with an SM-like Higgs boson coupling can surpass others in the long run. Using a convenient parametrization, we demonstrate that the alignment limit for CP-conserving 3HDMs takes on the same analytic structure as that in the case of 2HDMs. Using the example of a $Z_3$-symmetric 3HDM, we illustrate how such alignment conditions can be efficiently implemented for numerical analysis in a realistic scenario.

Inert dark matter in three Higgs doublet model: a blind spot narrative
In a Z3 x Z2-symmetric three-Higgs-doublet model with one inert doublet, the tree-level dark matter-nucleon scattering cross-section can vanish in a blind spot set by the dark sector mass splitting.
